摘要:

设计并合成了3 个新的受体-给体-受体(A-D-A)构型上转换荧光分子,用傅里叶变换红外光谱、核磁共振氢谱、质谱和元素分析进行了表征. 测定了它们在不同溶剂中的线性吸收光谱、单光子荧光光谱和荧光量子产率. 以飞秒激光作为光源,研究了它们的双光子吸收和上转换荧光特性. 结果表明:该类化合物的荧光量子产率为0.20-0.68,双光子吸收截面为16×10-50-101×10-50 cm4·s·photon-1,具有较强的蓝色上转换荧光发射.

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, single-photon 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 0.20-0.68, the two-photon absorption cross-sections were 16×10-50-101×10-50 cm4·s·photon-1, and they exhibited strong blue up-converted fluorescence.

Key words: A-D-A molecule, Synthesis, Two-photon absorption, Up-converted fluorescence
