  Accelerated Luminophore Discovery through Combinatorial Synthesis

  摘要：

  A method for accelerating the discovery of ionic luminophores using combinatorial techniques is reported. The photophysical properties of the resulting transition-metal-based chromophores were compared against a series of analogous, traditionally prepared species. The strong overlap between these two sets confirms the identity of the parallel synthesis products and supports the truthfulness of the combinatorial results. Further support for the combinatorial method comes from the adherence of these complexes to the energy gap law. The relationship between the structure of a complex and its photophysical properties was also considered, and static DFT calculations were used to assess whether it is feasible to predict the luminescent behavior of novel materials.

  complex organic reactions often involves the influence of multiple stereocontrol elements. The interaction among these can often result in the observation of significant cooperative effects that afford different rates and selectivities between the matched and mismatched sets of stereodifferentiating chiral elements. The elucidation of matched/mismatched effects in ground-state chemical reactions was a critically

  复杂有机反应中的立体诱导通常涉及多种立体控制元件的影响。这些之间的相互作用通常可以导致观察到显着的协同效应，这些效应在匹配和不匹配的立体分化手性元素组之间提供不同的速率和选择性。阐明基态化学反应中的匹配/不匹配效应是现代立体控制合成成熟过程中至关重要的主题。然而，用于控制光化学反应的稳健方法的开发是一个相对较新的发展，并且以前没有记录过激发态对映选择性光反应中类似的协同立体控制效应。在此，我们描述了一种串联手性光催化剂/布朗斯台德酸策略，用于乙烯基吡啶的高度对映选择性[2 + 2]光环加成。重要的是，匹配和不匹配的手性催化剂对在一系列偶联伙伴中表现出不同的反应速率和对映选择性。我们没有观察到催化剂之间基态相互作用的证据，并得出结论，这些效应是由它们在瞬态激发态组装中的合作行为引起的。这些结果表明，类似的匹配/不匹配效应在其他类型的对映选择性双催化光化学反应中可能很重要。
