Recent works of the Laboratory are reviewed in terms of modern concepts on the nature of primary photoprocesses in reaction centers of photosynthesis. The main feature of the primary charge separation in reaction centers is the fast (within several picoseconds) electron transfer between the pigments of chlorophyllous nature followed by electron transfer stage to nonchlorophyllous electron carriers for several hundreds of picoseconds The primary charge separation is determined by the ability of excited chlorophyll and its analogues to be reversibly oxidized or reduced as well as by peculiar molecular arrangement of pigment system in reaction centers. The stabilization of photochemically generated electron and the hole is realized at the expense of its spatial separation and some loss of energy in the course of electron transfer.
根据光合作用反应中心初级光过程本质的现代概念,对该实验室最近的研究工作进行了综述。反应中心初级电荷分离的主要特征是叶绿素性质的色素之间快速(在几皮秒内)的电子转移,随后是几百皮秒的电子转移至非叶绿素电子载体阶段。初级电荷分离取决于激发态叶绿素及其类似物可逆氧化或还原的能力,以及反应中心色素系统独特的分子排列。光化学产生的电子和空穴的稳定是通过其空间分离以及电子转移过程中的一些能量损失来实现的。
