PROBLEM TO BE SOLVED: To provide a new silsesquioxane polymer having an optically reactive group and method for producing the same, and to provide a refractive index converting material and light-heat energy converting and accumulating material. SOLUTION: The silsesquioxane polymer is composed of a repeating unit represented by formula (1), and the method for producing the same comprises reaction of the polymer composed of the specific repeating unit and a specific compound. [In the formula R<SP>1</SP>is a group represented by formula (a). n is a repeating number. In the formula (a) R<SP>2</SP>is a group represented in either one of formula (a-1) to formula (a-9)]. [In the formula (a-5), R<SP>3</SP>is H, a 1-10C alkoxy group, a 1-10C cycloalkoxy group, a 1-10C alkyl group or a -CF<SB>3</SB>group. In the formula (a-8), R<SP>4</SP>is H, a 1-10C alkyl group, a 1-10C alkoxy group or a dimethyl amino group.]. COPYRIGHT: (C)2006,JPO&NCIPI
