Abstract

Three D-π-A type pyridinium salts based on dipicolinate were synthesized. Compared to the corresponding neutral chromophores, enhanced two-photon absorption activity and water solubility were obtained. When measured by the Z-scan technique at 800 nm, the three molecules display considerably high values of two-photon absorption cross-section. The two-photon absorption cross-section values were found to be in the range 2421-25,318 GM. In addition, the three molecules exhibit pronounced negative solvatochromism and possess absorption spectral sensitivities to pH and to changes in the water content of tetrahydrofuran.
