  日期：2004.10.1

  [reaction: see text] An overall stereoconservative protection and deprotection method of amino and carboxyl groups is presented. N-Phthaloyl N'-alkyl secondary amides of alpha-amino acids can be generated from corresponding N-phthaloyl amino acids by coupling reaction of N-alkylamines using mixed anhydride method. These secondary amides can be transformed by thermal rearrangement of intermediate nitrosoamides

  β-carbonyl substituent creates a structural buffer between the donor and the surrounding solvent. Through computational and experimental analyses, it is demonstrated that the β-carbonyl simultaneously attenuates two distinct solvent-dependent quenching mechanisms. Using the β-carbonyl substituent, improvements in the photophysical properties of commonly used D-A fluorophores and their enhanced performance

  尽管有机供体-受体（DA）分子广泛应用于多个领域，但由于固有的极性敏感性会抑制光化学过程，因此可能会限制更多DA分子的应用。本文介绍了一种简便的化学修饰方法，可通过添加基于β-羰基的极性取代基来减弱溶剂依赖的激发态猝灭机理。结果揭示了一种机制，其中β-羰基取代基在供体和周围溶剂之间产生结构缓冲。通过计算和实验分析，证明了β-羰基同时减弱了两种不同的溶剂依赖性猝灭机理。使用β-羰基取代基
