Abstract

Three new acceptor-donor-acceptor (A-D-A) up-converted fluorescent molecules were designed and synthesized. Their structures were characterized using Fourier transform infrared and hydrogen nuclear magnetic resonance spectroscopy, mass spectrometry, and elemental analysis. The linear absorption spectra, singlephoton excited fluorescence spectra, and fluorescence quantum yields were measured in different solvents. The two-photon absorption and up-converted fluorescent properties were studied using a femtosecond laser. The results showed that the fluorescence quantum yields were 0.200.68, the two-photon absorption cross-sections were 16×10-101×10 cm4∙s∙photon-1, and they exhibited strong blue up-converted fluorescence.
