SOLUTION OF BINUCLEAR METAL COMPLEX PIGMENT, PHOTOELECTRIC CONVERSION DEVICE USING THE SOLUTION AND PHOTOCHEMICAL CELL

摘要

PROBLEM TO BE SOLVED: To provide a photoelectric conversion device prepared by using a light-resistant and oxidation and reduction-resistant solution of a metal complex pigment having a high light absorption coefficient and excellent electron mobility and a photochemical cell using the device.

SOLUTION: The binuclear metal complex pigment solution is stable against light and electrically and contains a metal complex pigment solution prepared by dissolving an asymmetric binuclear metal complex having a gas generating temperature of 280°C or higher and expressed by general formula: (L1)2M1(BL)M2(L2)2(X)nand semiconductor particles prepared. M1and M2are each a transition metal; L1and L2are each a polydentate chelate-type ligand, L1and L2are different, two L1's may be different from each other and so are two L2's ; BL is a crosslinked ligand having at least two ring structures containing heteroatoms; coordination atoms coordinated with M1and M2are included in these ring structures; X is a paired ion; n is the number of paired ions necessary to neutralize the charge of the complex.
