phenanthrene (DCPP), a commodity chemical that can be prepared at an industrial scale, was used as a photocatalyst in lieu of Ru or Ir complexes in C–X (X = C, N, and O) bond-forming reactions under visible-light irradiation. In these reactions, [DCPP]n aggregates were formed in situ through physical π–π stacking of DCPP monomers in organic solvents. These aggregates exhibited excellent photo- and electrochemical
在这项研究中,可以以工业规模制备的一种商品化学品2,3-二氰基吡嗪并菲(DCPP)用作光催化剂代替C–X中的Ru或Ir络合物(X = C,N和N)。 O)在可见光照射下形成键的反应。在这些反应中,[ DCPP ] n聚集体通过有机溶剂中DCPP单体的物理π–π堆叠原位形成。这些聚集体表现出优异的光化学性能,包括可见光响应(430 nm),激发态寿命长(19.3μs),激发态还原电位高(E red([ DCPP ] n * / [ DCPP] n · –)= +2.10 V vs SCE),并且还原稳定性好。[ DCPP ] n聚集体作为通用的可见光光催化剂的应用已在脱羧C-C交叉偶联,酰胺化和酯化反应中得到证明。
