Abstract: Our long term goals are to (i) achieve both molecular electronic and optoelectronic wires based on metal alkynyl compounds, and (ii) understand the mechanism charge / energy transfer therein. Recent work has been focused on the Chemistry of earth-abundant 3d metal complexes supported by polyaza-macrocycles (L), primarily cyclam and its derivatives. A number of Ni(II) complexes of C-substituted cyclam have been developed and some of which are far more efficient electro-catalysts for CO2 reduction than [Ni(cyclam)]2+. In terms of metal-alkynyl complexes, a rich variety of M(L)(C2R)X, M(L)(C2R)2 and M(L)(C2R)(C2R') type compounds with M as Cr, Fe, Co and Ni has been uncovered. As a special case of the latter type complexes, donor-bridge-acceptor compounds have been prepared and the dynamics of photo-induced electron transfer is being investigated.
 
Brief Biography: Tong Ren received his B.S. (Nanjing Forestry) and M.S. (Jilin) in chemistry in China (1981 and 1984) and his Ph.D. in inorganic chemistry from Texas A&M University under the supervision of late F. Al Cotton (1990). He held postdoctoral appointments at Texas A&M with Cotton (1991) and MIT with Stephen J. Lippard (1991–3). He was an assistant professor at Florida Institute of Technology (1993-8), an associate professor at the University of Miami (1998-2005), and has been a full professor at Purdue University since 2005. Between 2011 and 2013, he was a Program Director at the National Science Foundation, managing chemical synthesis and chemical catalysis portfolio. Research interests in his laboratory include organometallic molecular wires, mitigation of hazardous chemicals and sustainable chemistry.
