TECHNOLOGY FOCUS - ELECTRONICS - Preferred Structure: The photoelectric conversion element has photoreceptor layer, charge-transfer material layer (3), and counter electrode (4) laminated in order on electroconductive support (1).    TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preparation: No general preparation given. Preferred Complex: The complex (I) is chosen from formulae (Ia)-(Ij).

Preferred Definitions:    rings (A-D)=benzene ring, naphthalene ring, biphenyl ring, 1,3-diphenyl benzene ring, 1-phenyl-naphthalene ring, 2-phenyl-naphthalene ring, anthracene ring, phenanthrene ring, naphthacene ring, pentacene ring, quinoxaline ring, benzothiophene ring, thieno thiophene ring, bithiophene ring, ( pi )-electron insufficient heteroaryl, or bonded ( pi )-electron insufficient heteroaryl;and    M=copper, zinc, lead, nickel, tin, silicon, cobalt, ruthenium, palladium or vanadyl.    EXAMPLE - (In g) Dimethylsulfoxide (3 ml), 4-nitrophthalonitrile (0.2) and diisopropylamine (0.47) were reacted to obtain an intermediate (A) (0.03). 4-Iodophthalonitrile (0.13), 4-(methoxycarbonyl)phenylboronic acid (0.18), 1,4-diazabicyclo(2.2.2)octane (0.5 ml), cesium carbonate (0.54) and palladium acetate (0.03) were heated to 110 degrees C and extracted with diethyl ether to obtain intermediate (B) (0.08). The intermediate (A) (0.47), intermediate (B) (0.13), n-pentanol (6 ml), zinc chloride (0.14) and 1,8-diazabicyclo(5.4.0)-7-undecene (0.5 ml) were heated at 140 degrees C to obtain intermediate (C) (0.17). The intermediate (C) (0.11), tetrahydrofuran (5 ml) and 1.0 M sodium hydroxide aqueous solution (1 ml) were heated to 70 degrees C and stirred for 25 hours. The reaction mixture was concentrated and the residue was washed with water. The insoluble substance was filter-separated at 100 degrees C and a metal complex dye (0.08) was obtained.
