TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preferred Compounds: The photoelectric conversion layer further contains a charge-transport agent (5). The conductive polymer is formed using crosslinking composition containing aromatic reactant chosen from aromatic carbonyl compound having carbonyl group(s) as reactive site, aromatic polyamine having amino groups as reactive site, and aromatic heterocyclic compound having unmodified ( alpha )-carbon as reactive site adjacent to heteroatom of heterocyclic ring. When the aromatic reactant is an aromatic polyamine, the aromatic carbonyl compound is an aromatic polycarbonyl compound has carbonyl groups as reactive site, and at least one of aromatic polycarbonyl compound and aromatic polyamine has three or more reactive sites. When the aromatic reactant is an aromatic heterocyclic compound, the aromatic carbonyl compound is an aromatic aldehyde compound having formyl group(s) as reactive site. The number of formyl groups of the aromatic aldehyde compound is 2 or more. The number of unmodified ( alpha )-carbon of the aromatic heterocyclic compound is 3 or more. When the aromatic reactant is a combination of aromatic polyamine and aromatic heterocyclic compound, the aromatic carbonyl compound is an aromatic polyaldehyde compound having formyl groups as reactive site. The aromatic carbonyl compound is of formula (I). The aromatic polyamine compound is of formula (II). The aromatic heterocyclic compound is of formula (III).L=linker;A=aryl;R1=carbonyl-containing group;R2=non-reactive group;n=0 or 1;k1,a=1 or more;k2=0, or 1 or more;p=1 when n is 0, and 2 or more when n is 1;R3=amino;R4=H, amino, mercapto or hydroxy;Het=heteroaryl;X=heteroatom;R5=non-reactive group;andr=0-3.When n is 0, a is 2 or more.
