Semiconductor particle sensitized with methine dye
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 &#8212;CR3&boxH;CR4&#8212;; when X1 is a single bond, Y1 is &#8212;O&#8212;, &#8212;S&#8212;, &#8212;Se&#8212;, &#8212;NR5&#8212;, &#8212;CR6R7&#8212; or &#8212;CR8&boxH;CR9&#8212;; when X1 is &#8212;CR3&boxH;CR4&#8212;, Y1 is a single bond; when X2 is a single bond, Y2 is &#8212;O&#8212;, &#8212;S&#8212;, &#8212;Se&#8212;, &#8212;NR5&#8212;, &#8212;CR6R7&#8212; or &#8212;CR8&boxH;CR9&#8212;; when X2 is &#8212;CR3&boxH;CR4&#8212;, 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 &boxH;L1&#8212;Bo, &boxH;L2&boxH;Ak or &boxH;L3&#8212;Ar. A photoelectric material using the particles and a photoelectric conversion device using the material are also disclosed.
