摘要：

The nonlinear optical (NLO) properties of sandwich-type mixed tetrapyrrole europium double- and triple-decker complexes Eu(Pc)(TPYRP) (1) and Eu-2(Pc)(2)(TPYRP) (2) [Pc = unsubstituted phthalocyaninate, TPYRP = 5,10,15,20-tetrakis(1-pyrenyl)porphyrinate] were investigated by Z-scan experiments in CHCl3 solution at 1064 nm wavelength, showing enhanced third-order NLO properties compared with metal free phthalocyanine, porphyrin, and pyrene. Strong intramolecular pi-pi interaction and two-photon resonance are considered responsible for the large optical nonlinearity. The third-order NLO response of double-decker 1 is larger than that of triple-decker 2 probably associated with the unpaired electron in the former double-decker compound. (C) 2012 Elsevier Ltd.
