ABSTRACT:
The present invention provides a silicon compound represented by Formula (1) and a polymer obtained by using the same, and this makes it possible not only to obtain an organic-inorganic composite material having a distinct structure but also to control the structure of the above polymer as a molecular aggregate.wherein R1is a group independently selected from hydrogen, alkyl having a carbon atom number of 1 to 40, substituted or non-substituted aryl and substituted or non-substituted arylalkyl; in this alkyl having a carbon atom number of 1 to 40, optional hydrogens may be substituted with fluorine, and optional —CH2— may be substituted with —O—, —CH═CH—, cycloalkylene or cycloalkenylene; in alkylene in this arylalkyl, optional hydrogens may be substituted with fluorine, and optional —CH2— may be substituted with —O— or —CH═CH—; and A1is a group having an α-haloester group.
