A silsesquioxane derivative represented by the formula (1): (1) wherein R1 is hydrogen, alkyl, aryl, or arylalkyl; R2 and R3 each is alkyl, phenyl, or cyclohexyl; and A is a group having the ability to cause monomers to begin to polymerize. When the silsesquioxane derivative is used to form a polymer, a new organic/inorganic composite material is obtained. |
