Definitions
- This invention concerns photosensitizers, more particularly it concerns novel transition metal photosensitizers.
- the currently recommended dye-type sensitizer is cis-di(thiocyanato)bis(2,2'-bipyridine-4,4'- dicarboxylate) ruthenium(II), (I) known as "RuN3 dye".
- RuN3 dye has an excellent photon to electron conversion, and very high stability. Certain metallated phthalocyanines have been tested, but their electrical output is not nearly as high as the RuN3 dye. Despite the high efficiency and output of photovoltaic devices based on the RuN3 dye, and their particularly useful property of continuing to have high output under cloudy conditions (unlike silicon-based photocells), they do have a purple colour.
- photosensitizers for use with TiO 2 -based photovoltaic devices, especially those which absorb at longer wavelengths than RuN3.
- Such sensitizers may absorb in the near infra-red region and may possibly be used to make optically transparent photovoltaic devices useful for example in windows or other glazed areas.
- photosensitizer such as RuN3
- solar energy from a wider spectrum may be converted to electricity, giving an increased efficiency for the device.
- the present invention provides novel transition metal phthalocyanine-type derivatives of formula I,
- each X is hydrogen, alkyl, alkoxy, hydroxy, aryl, substituted aryl, alkylthio, ether, thioether, amino or mono- or di-substituted amino or adjacent X's may together form -C 4 H 4 (Y) n - or
- Y is alkyl, alkoxy, hydroxy, aryl, substituted aryl, alkylthio, ether, thioether, amino or mono- or di-substituted amino and n has a value from 0-4,
- each of R and R' is independently either a first bonding ligand incorporating a functional group which permits bonding to TiO 2 or other semiconductor to be sensitized and which ligand can conduct an electron from an excited state of the phthalocyanine structure to the conduction band of TiO 2 or other semiconductor when bonded thereto, or a second ligand which does not labilise the bond between M and the first bonding ligand, providing at least one of R and R' is said first bonding ligand, and Q is nitrogen or -CZ- where Z is independently hydrogen, alkyl, alkoxy, hydroxy, aryl, substituted aryl, alkylthio, ether, thioether, amino or mono- or di-substituted amino,
- M is Ru
- Suitable first bonding ligands R or R' incorporate phosphonic acid, carboxylic acid, or possibly sulphonate groups.
- R or R' incorporates an amine, it may be a straight or branched chain amine, or a cyclic or an aromatic amine such as pyridine, imidazole or triazole.
- the ligands may be mono- or poly-substituted with the afore-mentioned groups.
- Suitable ligands include 4-pyridine ethane-sulphonate, 3-pyridine sulphonate, pyridine-3- phosphonic acid, imidazole-4,5-dicarboxylic acid, l,2,3-triazole-4,5-dicarboxylic acid, 4-diphenylphosphinobenzoic acid, tris(4-carboxyphenylphosphine), 4-isocyanobenzoate, nicotinic acid, and especially preferred are pyridine-3,4-dicarboxylate and pyridine-4- phosphonic acid.
- the TiO 2 bonding group may be separated from the metal binding site by a suitable linking group, eg
- ligand R or R' when bonded to TiO 2 , provides a ⁇ bonding system.
- R or R' is a said second ligand, it may be CO or, preferably, a nitrogen donor such as an aliphatic, especially branched chain aliphatic, amine or a cyclic amine especially an aromatic amine.
- Such second ligands may carry substituents.
- X, Y or Z is alkyl or alkoxy, preferably each alkyl or alkoxy group has up to 8 carbon atoms, and may be branched chain.
- the compound may be in salt form, in which case the counterions are desirably K + , Na + or quaternary ammonium.
- the compounds of formula I are novel, and may be prepared by a process comprising reacting a metal phthalocyanine compound of formula II,
- M, Q and X are as defined above, and A is an amine, preferably a pyridine group, CO (carbon monoxide) or a co-ordinating solvent, for example benzonitrile, with a salt of the ligand R, and isolating the product compound of fo ⁇ nula I.
- A is an amine, preferably a pyridine group, CO (carbon monoxide) or a co-ordinating solvent, for example benzonitrile, with a salt of the ligand R, and isolating the product compound of fo ⁇ nula I.
- the starting metal phthalocyanine or naphthalocyanine is mixed in an organic solvent, such as toluene, ethanol or 2-methoxy ethanol or a mixture of a water- miscible organic solvent and water, such as an aqueous tetrahydrofuran, or immiscible solvent mixtures such as chloroform and water, with an excess, for example 2-10 fold stoichiometric, of the axial ligand, under an inert atmosphere, such as argon.
- the reaction is carried out desirably by heating, for example at reflux for about two days.
- the product may be isolated by the addition of a co-solvent to the reaction mixture. If required, the solubility of the product may be enhanced by exchanging the counterions, in generally known manner.
- the axial ligands R in the compounds of the invention are not identical, it may be appropriate to prepare them by starting from a compound of formula II in which A is an amine suitable to act as the second ligand R. One of the ligands A may then be displaced with a salt of first ligand R in analogous manner to that described above.
- a compound of formula I in which both ligands R are identical aromatic amines may be prepared and one ligand R may be displaced using one equivalent of a non-aromatic amine.
- the present invention by incorporating a bonding axial ligand, instead of the conventional substitution at the periphery of the Pc (see Sandoz WO 94/05025), has advantages and facilitates the synthesis of isomerically pure compounds.
- RuN3 dye indicates that purity of the dye is both important and difficult to obtain.
- the redox potential of the ground and excited states need to be carefully optimised, as does the ⁇ max of absorption.
- the present invention permits improved selection and "fine tuning" of properties for optimum photosensitization by substitution at the periphery of the phthalocyanine structure.
- the novel compounds have been found to be active in photosensitizing activity for TiO 2 -based photovoltaic devices as described hereafter. Moreover, some at least of the compounds possess a pleasing green colour, which increases the opportunity for commercial use of the compounds as photosensitizers.
- the novel compounds of the invention may be used in photovoltaic devices in generally known manner. The compounds show significantly improved performance over the previously specifically described phthalocyanines in the Sandoz WO 94/05025 and in our WO 93/09124, as will be shown hereafter.
- the invention further provides a photovoltaic device based upon a film of TiO 2 , wherein the TiO 2 has deposited thereon a compound according to general formula I.
- RuCl 3 .xH 2 O (43.37% Rh, 2.64g, 0.113mmol) was boiled in 1-pentanol (20ml) until a deep blue solution was obtained. This was added to a refluxing solution of 3,6-dimethylphthalonitrile (8.85g, 0.0566mol) and hydroquinone (0.62g, 0.0056mol) in 1-pentanol (60ml) under nitrogen. Ammonia gas was passed through the reaction flask and refluxing continued for 3 days.
- the compound a, '-(n-decyl) 8 PcRu(pyridine-3,4-dicarboxylic acid) 2 is prepared in a similar manner.
- Complexes containing a different ligand R' may be obtained by displacement of the carbonyl ligand by photolysis in the presence of excess ligand R' according to known methods [D Dolphin, B R James, A J Murray and J R Thornback, Can J Chem (1980), 58, 1125].
- the compound was deposited by dipping a mesoscopic anatase film (thickness ca 10 ⁇ , coated onto conducting glass, LOF TEC 10, fluorine-doped SnO 2 sheet resistance 10 ohm/square) as previously described in J Am Chem Soc, 1993, 115, 6382) for several hours in a 3xl0 "4 M solution in ethanol containing 50mM 3 ⁇ ,7 ⁇ -dihydroxy-5 ⁇ -cholic acid (Cheno) and 2.5% DMSO.
- Cheno is necessary to avoid surface aggregation of the sensitiser.
- the visible band in the abso ⁇ tion spectrum of compound A is red shifted by lOnm upon adso ⁇ tion.
- the occurrence of electron transfer was further confirmed by time resolved nanosecond Nd-YAG laser experiments shown in the inset of Figure 1.
- the end of pulse transient spectrum indicates bleaching of the ground state abso ⁇ tion of compound A and the appearance of new features in the wavelength range of 700 to 800nm and the 480 to 580nm. These bands are attributed to the formation of the cation radical of the phthalocyanine.
- the recovery of the ground state spectrum due to charge recombination occurs on a time scale of several hundred microseconds indicating that re-capture of the conduction band electron by the oxidised dye is a relatively slow process.
