光敏化反应为当前日趋活跃的研究领域,在探讨光敏化反应机理时,经常涉及到分子受激发后的状态变化及能量传递等重要过程。70年代以来,激光闪光光解技术已广泛地用于观测光化学反应中各种瞬态光谱及其变化的情况,为研究和探讨反应机理提供了新的途径。我们利用激光闪光光解技术对二苯甲酮光敏化一系列萘基烷烃衍生物的三重态-三重态
Photo-sensitization is an increasingly active research field at present. When discussing the mechanism of photo-sensitization reaction, it often involves the state change after molecular excitation and the important process of energy transfer. Since the 1970s, laser flash photolysis has been widely used in the observation of various transient photochemical reactions and their changes in the situation, which provides a new way for the study and discussion of the reaction mechanism. We use the laser flash photolysis of benzophenone photosensitized a series of naphthalene alkane derivatives triplet - triplet state
