Semiconductor particle sensitized with methine dye

Abstract

A semiconductor particle has a surface on which a methine dye is adsorbed. The methine dye is represented by the formula (I). in which Q1 is a tetravalent aromatic group; each of X1 and X2 independently is a single bond or —CR3═CR4—; when X1 is a single bond, Y1 is —O—, —S—, —Se—, —NR5—, —CR6R7— or —CR8═CR9—; when X1 is —CR3═CR4—, Y1 is a single bond; when X2 is a single bond, Y2 is —O—, —S—, —Se—, —NR5—, —CR6R7— or —CR8═CR9—; when X2 is —CR3═CR4—, Y2 is a single bond; each of R1 and R2 independently is an aliphatic group or an aromatic group; and each of P1 and P2 independently is ═L1—Bo, ═L2═Ak or ═L3—Ar. A photoelectric material using the particles and a photoelectric conversion device using the material are also disclosed.
