Photocatalysts are powerful tools for effecting chemistry integral to renewable energy and organic synthesis. Photocatalysis has already enabled an impressive range of small molecule and carbon functionalization reactions, and novel applications are continuously being discovered in this dynamic field. However, Ru- and Ir- compounds, are frequently used as photosensitizers for many of these processes. Significant research efforts have focused on replacing these noble metal complexes with inexpensive, earth-abundant alternatives. We have developed a series of first-row transition metal complexes of the macrocyclic Mabiq ligand. The redox and photochemical properties of the M-Mabiq complexes make them promising photoredox catalysts. The proposed research will focus on studies to examine the detailed photochemical properties of a series of mono- and bi-metallic Mabiq complexes, and the broader catalytic capacity of the complexes. The aim of the research is to 1) probe the nature and properties of the M-Mabiq excited states; 2) explore the reaction scope and opportunities for dual photoredox catalysis; 3) synthesize and study bimetallic Mabiq complexes for bifunctional photocatalysis. The project will employ a combination of synthesis, spectroscopy, computational work and reactivity studies. The research will contribute to t

光催化剂是影响化学成分的强大工具，可再生能源和有机合成。光催化已经实现了令人印象深刻的小分子和碳官能化反应，并且在这个动态场中不断发现新的应用。但是，RU-和IR-化合物经常用作许多此类过程的光敏剂。重大的研究工作集中在用廉价，丰富的替代品代替这些贵族金属络合物。我们已经开发了一系列大环Mabiq配体的第一行过渡金属复合物。 M-Mabiq复合物的氧化还原和光化学特性使它们有望具有光电毒催化剂。拟议的研究将集中于研究一系列单金属MABIQ复合物的详细光化学特性以及复合物的更广泛的催化能力。研究的目的是1）探测M-Mabiq激发态的性质和性质； 2）探索反应范围和双重光电毒素催化的机会； 3）合成和研究双金属MABIQ复合物进行双功能光催化。该项目将采用合成，光谱，计算工作和反应性研究的结合。 这项研究将有助于
