摘    要:详细研究了HA在分子筛MCM-41中的光谱特性,指定其在强激光脉冲激发下产生了双光子吸收,指认长波荧光发射带为激发态质子转移荧光。结果表明只有在强光作用下才发生激发态质子转移。

关 键 词:竹红菌甲素  光动力疗法(PDT)  激发态分子内质子转移(ESIPT)  分子筛  吸收光谱  荧光光谱

Abstract:The absorption and fluorescence spectrum of HA dispersed in sieves (MCM-41) are studied in detail. HA is designated to produce two-photon absorption under strong pulse laser excitation, and long wavelength fluorescence emission band is designated as transferring fluorescence of excited state proton. The results show that the transferring could be achieved only under strong pulse.
Keywords:hypocrellin A photodynamic therapy (PDT) excited state intramolecule proton transfer (ESIPT) sieves absorption spectrum flurescence spectrum
