UNSYMMETRICALLY SUBSTITUTED FLUORENES FOR NON-LINEAR OPTICAL APPLICATIONS

摘要

Compounds having non-linear optical activity of general formula (I), wherein D and A are electron donor and acceptor groups, respectively, R?1 and R2¿ are aromatic bridging groups, X and Y are preferably groups capable of partaking in polymerization reactions are suitable for use in polymer-based light modulator devices.
