Tuning Second-Order Optical Nonlinearities in Push-Pull Benzimidazoles

The synthesis and full characterization of new chromophores with second order optical nonlinearities containing the 2phenyl-(5,6)-nitrobenzimidazole group is reported. Starting from 2-{4-[(4-N,N-dihydroxyethylamino)phenylazo]phenyl}5(6)-nitrobenzimidazole, a combined theoretical and experimental approach, including theoretical computations of second order… CONTINUE READING
