Abstract:
1. An optical waveguide comprising a polymer obtained by using a silsesquioxane derivative represented by the formula (1-0) wherein R 0 independently represents: hydrogen, alkyl having 1 to 40 carbon atoms in which hydrogen may optionally be replaced by fluorine and —CH aryl in which hydrogen may optionally be replaced by halogen, or by alkyl having 1 to 20 carbon atoms in which hydrogen may optionally be replaced by fluorine and —CH arylalkyl in which hydrogen in the aryl may optionally be replaced by halogen or alkyl having 1 to 20 carbon atoms, and hydrogen in the alkylene of the arylalkyl may optionally be replaced by fluorine, and —CH Y is a group represented by the formula (a) or (b) wherein X in each of the formulae (a) and (b) independently represents a group selected from hydrogen, chlorine, a group defined in the same way as R 0 , or a group having any one of —CH═CH—, —C≡C—, —OH, —COOH, —COO—, 2-oxapropane-1,3-dioyl, oxilanyl, oxilanylene, oxetanyl, oxetanylene, 3,4-epoxycyclohexyl, —SH, —NH—, —NH 2 , —CN, and —O—, and at least one of X is a reactive group selected from the above-defined group, and Z in the formula (b) represents a single bond, —O—, or —CH
