Abstract

Functionalized distyrylbenzene analogs 2 and 3, bearing a tris-(2-pyridylmethyl)amine-based receptor for Zn2+, were synthesized by a Horner-Emmons-Wittig coupling reaction. It has been found that Zn 2+ complexation induces changes in the linear absorption spectrum that enhance a nonlinear sequential two-photon absorption of nanosecond pulses at 532 nm. This absorption was also found to depend on the nature of the substituent at the side benzene ring of the styrylbenzene structure.
