摘　　要：Quantum chemistry calculations are performed to study the properties of newly designed polymers with alternative electron-donating and electron-withdrawing groups.The nonlinear optical susceptibilities of these special polymers increase considerably with aggregation number,while their electron absorption spectra show little red shift.This kind of structures is helpful to resolve the conflict between NLO response and transparence.Quantum chemistry calculations are performed to study the properties of newly designed polymers with alternative electron-donating and electron-withdrawing groups.The nonlinear optical susceptibilities of these special polymers increase considerably with aggregation number,while their electron absorption spectra show little red shift.This kind of structures is helpful to resolve the conflict between NLO response and transparence.
