Polypyridyl transition metal complexes represent one of the more thoroughly studied classes of molecular catalysts towards CO reduction to date. Initial reports in the 1980s began with an emphasis on 2nd and 3rd row late transition metals, but more recently the focus has shifted towards earlier metals and base metals. Polypyridyl platforms have proven quite versatile and amenable to studying various parameters that govern product distribution for CO reduction. However, open questions remain regarding the key mechanistic steps that govern product selectivity and efficiency. Polypyridyl complexes have also been immobilized through a variety of methods to afford active catalytic materials for CO reductions. While still an emerging field, materials incorporating molecular catalysts represent a promising strategy for electrochemical and photoelectrochemical devices capable of CO reduction. In general, this class of compounds remains the most promising for the continued development of molecular systems for CO reduction and an inspiration for the design of related non-polypyridyl catalysts.
多吡啶过渡金属配合物是迄今为止针对 CO 还原研究最深入的一类分子催化剂。20 世纪 80 年代的初步报告主要集中在第 2 周期和第 3 周期的后过渡金属上，但最近的研究重点已转向更早的金属和基础金属。多吡啶平台已被证明具有广泛的适用性，并且可以研究各种参数来控制 CO 还原的产物分布。然而，关于决定产物选择性和效率的关键机理步骤仍存在悬而未决的问题。多吡啶配合物也已经通过各种方法固定化，以提供用于 CO 还原的活性催化材料。虽然这仍然是一个新兴领域，但包含分子催化剂的材料代表了电化学和光电化学器件的一种很有前途的策略，这些器件能够进行 CO 还原。总的来说，对于 CO 还原分子体系的持续发展，这类化合物仍然是最有前途的，并且为相关非多吡啶催化剂的设计提供了灵感。
