The subject of the invention are new functionalized unsaturated double-decker derivatives of divinylsilsesquioxanes of the general formula 1, - R 1 are the same and stand for an aryl group containing from 1 to 2 rings, - R 2 are the same and stand for an alkyl group containing carbon atoms from C 1 to C 2 , substituted or unsubstituted aryl group containing from 1 to 2 rings, - R 3 are the same and stand for a substituted or unsubstituted aryl group containing from 1 to 2 rings or a group of the formula -R 4 -R 5 - where R 4 stands for an alkyl group containing carbon atoms from C 1 to C 3 , while R 5 stands for aryl group containing from 1 to 2 rings.
