自然界中,太阳能转化成化学能的最主要途径是光合作用过程。光合作用过程中担任把光能吸收转化成化学能的主要角色是含镁的卟啉类化合物——叶绿素。由于叶绿素起着如此重要作用,因此引起了很多科学工作者的兴趣。他们把叶绿素提取分离出来,测定了它的分子结构、化学物理性质。在1962年全合成了其中最重要的一种——叶绿素a。叶绿素在光合器官中有不同的存在状态,起着不同的作用。有的叶绿素起捕获光能的功能,它们吸收光能并将光能传递到作用中心去;有的处在作用中心,推动把光能转化成化学能的原初过程。要说明叶绿素是怎样和蛋白质、磷脂、质醌等复合在一起的,这种复合体是怎样发挥固定光能的功能的,这是近年来受到广泛重视的研究课题之一。很多人都想通过研究纯粹的叶绿素和它的衍生物的光化学物理性质,体外重组和模拟光合作用过程
In nature, the most important way to convert solar energy into chemical energy is the photosynthesis process. The main role of photosynthesis as a light energy conversion into chemical energy is the porphyrin containing magnesium - chlorophyll. As chlorophyll plays such an important role, it has aroused the interest of many scientists. They extracted the chlorophyll and determined its molecular structure, its chemical and physical properties. In 1962, the synthesis of one of the most important - chlorophyll a. Chlorophyll has different states of existence in photosynthetic organs and plays a different role. Some chlorophyll functions to capture light, which absorbs light and transmits it to the center of action; some is at the center of action, driving the original process of converting light energy into chemical energy. To explain how chlorophyll and protein, phospholipid, quinone and other compounds together, this complex is how to play the role of fixed light energy, which is widely studied in recent years, one of the topics. Many people want to study the photochemical properties of pure chlorophyll and its derivatives, recombine in vitro and simulate the process of photosynthesis
