Of noble descent: A fully noble‐metal‐free system for the photocatalyticreduction of water at room temperature has been developed. This system consists of CuI complexes as photosensitizers and [Fe3(CO)12] as the water‐reduction catalyst. The novel Cu‐based photosensitizers are relatively inexpensive, readily available from commercial sources, and stable to ambient conditions, thus making them an attractive

molarities of 3-33 M for formation of intramolecular H-bonds. This corresponds to a free energy penalty of 3-9 kJ mol(-1) for formation of a bimolecular complex in solution, which is consistent with previous estimates of 6 kJ mol(-1). This result can be used in conjunction with the H-bond parameters, alpha and beta, to make a reasonable estimate of the stability constant for formation of a multiply H-bonded
化学双突变循环已与新的 H 键合基序结合使用,用于量化多 H 键合复合物中的螯合协同性。双突变循环方法专门处理取代基、次级相互作用和变构协同作用对来自单个 H 键位点的自由能贡献的影响,并允许剖析由于与分子内非共价相互作用形成相关的螯合协同作用而产生的自由能贡献. 在四氯化碳、氯仿、1,1,2,2-四氯乙烷和环己烷中研究了两种不同的双 H 键基序,结果在所有情况下都相似,有效摩尔浓度为 3-33 M,用于形成分子内 H - 债券。这对应于在溶液中形成双分子复合物的 3-9 kJ mol(-1) 的自由能惩罚,这与先前估计的 6 kJ mol(-1) 一致。该结果可与 H 键参数 alpha 和 beta 结合使用,以合理估计在两个完全互补的伙伴之间形成多重 H 键复合物的稳定性常数,或设置上限互补性较差的系统预期的稳定性常数。
