Photoactive complexes of nonprecious transition metals, mainly including those in the first-row and partially the second-row of the Periodic table of elements, have received increasing attention in view of their low cost and long-term sustainability. They are recognized as promising alternatives to noble transition metal complex congeners that have been extensively studied in optoelectronic devices, artificial photosynthesis, photocatalysis, biodiagnostics, and therapeutics, etc. This review is devoted to a comprehensive summary on the classical and recent advances on photoactive nonprecious transition metal complexes, including photoactive Zr, V, Cr, Mo, and W complexes, Mn complexes and hybrids, Fe, Co, Ni, and Cu complexes, and Zn and Cd complexes and hybrids. A particular focus is given on the molecular design, modulation of photophysical and photochemical properties, and applications of the representative and lately-developed nonprecious metal complexes. In addition, a perspective on the future development in this field is provided at the end of this review.

Urea-bridged diferrocene: structural, electrochemical, and spectroelectrochemical studies

引用

Science China Chemistry 2015年第9期58卷 1444-1450页

作者： Zhong-liang gong Yu-Wu Zhong Beijing National Laboratory for Molecular Sciences CAS Key Laboratory of Photochemistry Institute of Chemistry Chinese Academy of Sciences

Urea-bridged diferrocene derivatives N,N?-diferrocenylurea(1) and N,N?-dimethyl-N,N?-diferrocenylurea(2) were prepared and characterized. Single-crystal X-ray analysis shows that Compound 1 has a trans-trans linear conformation whereas Compound 2 has a trans-cis conformation. Both compounds display two consecutive redox couples with, respectively, E1/2 of +0.29 and +0.42 V vs. Ag/Ag Cl for 1 and +0.31 and +0.50 V for 2. Spectroelectrochemical studies show the presence of distinct intervalence charge transfer(IVCT) transitions for the one-electron-oxidized mixed-valent Compound 1+, with an estimated electronic coupling parameter of 190 cm?1. By contrast, the one-electron-oxidized Compound 2+ shows much weaker IVCT transitions.

New insight into hydrogen bond-mediated electron transfer

引用

Science China Chemistry 2019年第8期62卷 927-928页

Electron transfer (ET) is one of the most fundamental processes in nature, biological systems, and optoelectronic devices. The in-depth ET investigations of synthetic materials are of great significance for the understanding of those occurring in natural systems. Mixed-valence (MV) compounds, consisting of two bridged redox motifs that are structurally identical but different in valence, provide an appealing platform for this purpose [1]. To date, a vast number of MV compounds have been synthesized and examined. However, successful or even partially successful examples of MV compounds with efficient electronic coupling and ET through a hydrogen bond are very limited [2,3]. The difficulty in building hydrogen bond-bridged MV compounds is mainly caused by the dynamic nature and elusive chargetransporting property of hydrogen bond and its decreased stability upon redox reactions.

21世纪以来,中国博物馆的大型原创性特展工作呈现良好的发展态势。南京博物院龚良院长指出,大型原创性特展作为博物馆为公众提供更好的文化服务的文化产品,既能衡量博物馆的发展活力,也有利于博物馆的可持续发展。博物馆应根据自身的定位和特色完善藏品体系,从而确定展览主题,制订展览规划。高校应该围绕研究公众、服务公众调整博物馆学的课程设置。试行中的理事会制度将有助于推动博物馆为公众提供高品质的文化服务、满足公众更高的精神文化需求。南京博物院近年大力推行策展人制度,鼓励策划大型原创性特展,重视并强调展示文物之间的相互关系。2016年度举办的"法老·王"展是一次用低票价、非营利的方法,举办了一个不用财政资金、为公众提供优质服务的高品质展览,并将展览作为文化创意产品的有益尝试,将为中国博物馆界提供一个可复制的成功案例。
