group (FPRPG) for carboxylic acids and alcohols. Carboxylic acids including amino acids were protected as their corresponding esters by coupling with FPRPG, perylen-3-ylmethyl. Photophysical studies of caged esters showed that they all exhibited strong fluorescence properties and their fluorescence quantum yields were in the range of 0.85–0.95. Irradiation of the caged esters using visible light (≥410 nm)
Perylen-3-ylmethyl被证明是一种用于羧酸和醇的新型荧光光可去除保护基(FPRPG)。包括氨基酸在内的羧酸通过与FPRPG脯氨酸-3-基甲基偶联而作为相应的酯得到保护。笼状酯的光物理研究表明它们都具有很强的荧光特性,其荧光量子产率在0.85-0.95范围内。使用可见光(≥410nm)在乙腈水溶液中对笼形酯进行辐照,可以释放出相应的羧酸,其化学成分较高(94-97%),量子产率为(0.072-0.093)。笼型酯在不同溶剂中的光解结果表明,溶剂对光释放速率有影响。此外,我们还探索了FPRPG的功能,
