PROBLEM TO BE SOLVED: To provide a modified silicon-containing material having a high refractive index. SOLUTION: A polymer material containing a bicyclic (2,2,1) ring system represented by the general formula (1), most preferably a bound bicyclic crosslinked structure such as a norbornyl group hanging from a siloxane skeleton. Crosslinked bicyclic-containing materials can exhibit good refractive index, transparency, gas permeability, and / or other properties and are suitable for use in a variety of applications.
