Abstract

Two photochromic dithiazolylethene-based derivatives (1a and 2a) incorporating a push–pull structural motif D–π–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)2·2a, Mn(hfac)2·2a and Ag(2a)2CF3SO3. Their crystal structures are determined.
