Herein, two monomers with different azulene moieties were designed and the polymers were synthesized through ring opening metathesis polymerization (ROMP). The azulenes are bicyclic non-benzenoid aromatics which exhibit strong dipole moments and significant nonlinear optical properties. The intrinsic absorption from azulene and aminobezoate was observed, the13246449 bytesapplication/pdfen-US薁降冰片烯高分子azulenenonlinear opticalHRSthesishttp://ntur.lib.ntu.edu.tw/bitstream/246246/257276/1/ntu-100-R98223115-1.pdf
