Synthesis and Evaluation of Third-Order Optical Nonlinearities of Model CompoundsContaining Benzothiazole, Benzimidazole and Benzoxazole Moieties

摘要

A series of model compounds containing benzothiazole, benzimidazole andbenzoxazole moieties were prepared and evaluated by femtosecond degenerate four-wave mixing techniques. Model compounds were evaluated as either solutions of various concentrations in tetrahydrofuran or as vacuum deposited films. In general, the trend toward nonlinearity was directly related to structural
