摘要: A luminescent bis(salicylaldiminato)zinc(II) Schiff-base complex, 1, is characterized by a concentration dependent second-order nonlinear optical response, related to the degree of aggregation complex in dichloromethane solution. The formation monomeric adduct, addition Lewis base, such as pyridine, concentrated solutions leads switch-on quadratic hyperpolarizability. This represents an unprecedented mode NLO switching molecular materials.
