Synthesis of Porphyrin-Fullerene Complexes

按照卟啉与富勒烯连接方式的不同,卟啉-富勒烯化合物可分为共价键连接和非共价键连接两种类型。共价键连接的卟啉-富勒烯化合物主要是通过环加成反应来合成,如1,3-偶极环加成反应、dIElS-AldEr环加成反应和bIngEl-HIrSCH环加成反应;非共价键连接的卟啉-富勒烯化合物主要是通过金属的轴向配位及氢键得到。本文综述了近年来不同类型的卟啉-富勒烯化合物的合成研究,着重介绍了共价键连接卟啉-富勒烯化合物的合成及应用前景,分析目前在合成方法上存在的问题,并对未来的研究提出了展望。Fullerenes have been found to be good acceptors,due to their unique three-dimensional structure and remarkably withdrawing electron.Porphyrins are frequently used as ideal donors for their π conjugate structure and plentiful π electrons.Also,they are good photosensitizers,and have wide absorbability in UV-vis region.Porphyrin-fullerene complexes become currently active fields for their promising value of mimics of the natural photosynthetic reaction centers and photoinduced electron transfer.This material is hopeful to be applied in photovoltaic cells and solar cells.In accordance with the different ways to connect porphyrin and fullerene,porphyrin-fullerene complexes can be divided into two types: covalently linked and non-covalently linked.Covalently linked porphyrin-fullerene complexes are synthesized mainly through cycloaddition reactions,such as the 1,3-dipolar cycloaddition reaction,Diels-Alder cycloaddition reaction and Bingel-Hirsch cycloaddition reaction.Non-covalently linked porphyrin-fullerene complexes are obtained maily through the axial coordination of metal and the hydrogen bonding.This review covers the recent progress in synthesis of different types of porphyrin-fullerene complexes,including the synthesis and application prospects of covalently linked porphyrin-fullerene compounds,existing problems in synthetic methods and further prospects in this field.巢湖学院院级项目(No.XLY-201009)资

Synthesis of Porphyrin-Fullerene Complexes

Fullerenes have been found to be good acceptors, due to their unique three-dimensional structure and remarkably withdrawing electron. Porphyrins are frequently used as ideal donors for their pi conjugate structure and plentiful pi electrons. Also, they are good photosensitizers, and have wide absorbability in UV-vis region. Porphyrin-fullerene complexes.become currently active fields for their promising value of mimics of the natural photosynthetic reaction centers and photoinduced electron transfer. This material is hopeful to be applied in photovoltaic cells and solar cells. In accordance with the different ways to connect porphyrin and fullerene, porphyrin-fullerene complexes can be divided into two types: covalently linked and non-covalently linked. Covalently linked porphyrin-fullerene complexes are synthesized mainly through cycloaddition reactions, such as the 1,3-dipolar cycloaddition reaction, Diels-Alder cycloaddition reaction and Bingel-Hirsch cycloaddition reaction. Non-covalently linked porphyrin-fullerene complexes are obtained maily through the axial coordination of metal and the hydrogen bonding. This review covers the recent progress in synthesis of different types of porphyrin-fullerene complexes, including the synthesis and application prospects of covalently linked porphyrin-fullerene compounds, existing problems in synthetic methods and further prospects in this field

类泛素蛋白及其中文命名

泛素家族包括泛素及类泛素蛋白,约20种成员蛋白.近年来,泛素家族领域取得了迅猛发展,并已与生物学及医学研究的各个领域相互交叉.泛素家族介导的蛋白质降解和细胞自噬机制的发现分别于2004和2016年获得诺贝尔奖.但是,类泛素蛋白并没有统一规范的中文译名. 2018年4月9日在苏州召开的《泛素家族介导的蛋白质降解和细胞自噬》专著的编委会上,部分作者讨论了类泛素蛋白的中文命名问题,并在随后的\"泛素家族、自噬与疾病\"(Ubiquitinfamily,autophagy anddiseases)苏州会议上提出了类泛素蛋白中文翻译草案,此草案在参加该会议的国内学者及海外华人学者间取得了高度共识.冷泉港亚洲\"泛素家族、自噬与疾病\"苏州会议是由美国冷泉港实验室主办、两年一度、面向全球的英文会议.该会议在海内外华人学者中具有广泛影响,因此,参会华人学者的意见具有一定的代表性.本文介绍了10个类别的类泛素蛋白的中文命名,系统总结了它们的结构特点,并比较了参与各种类泛素化修饰的酶和它们的生物学功能.文章由45名从事该领域研究的专家合作撰写,其中包括中国工程院院士1名,相关学者4名,长江学者3名,国家杰出青年科学基金获得者18名和美国知名高校华人教授4名.他们绝大多数是参加编写即将由科学出版社出版的专著《泛素家族介导的蛋白质降解和细胞自噬》的专家
