Abstract
The present inventors have obtained a PSQ derivative of a completely condensed type into which a functional group is readily introduced by using a novel PSQ derivative of an incompletely condensed type in which four alkaline metal atoms are bonded to silsesquioxane of a cage type having eight Si's. The above silsesquioxane derivative is represented by Formula (1). A silsesquioxane derivative to which alkaline metal atoms are bonded is represented by Formula (2). In Formula (1) and Formula (2), R is a group selected from alkyl, aryl and arylalkyl; Y is a group represented by Formula (a) or Formula (b); and M is a monovalent alkaline metal atom. X in Formula (a) and Formula (b) is hydrogen, halogen, a hydroxyl group or a monovalent organic group, and Z is —O—, —CH— or a single bond. The preferred organic group is a functional group or a group having a functional group.
