摘要：

Two photochromic dithiazolylethene- based derivatives ( 1a and 2a) incorporating a push - pull structural motif D - p - A are synthesized and structurally characterized. The photochemical reactions, which reversibly modify the connection between the electron donor and acceptor, result in simultaneous and effective photo- modulations of their NLO and fluorescent properties. The photo- switchable NLO behaviors are investigated theoretically by performing INDO calculations. The presence of chelating sites in 2a allows the synthesis of various metal complexes: Cu( hfac)(2)center dot 2a, Mn( hfac)(2)center dot 2a and Ag( 2a)(2)CF3SO3. Their crystal structures are determined.
