摘要

我们介绍了两种吡啶修饰（NCN）螯合铋配合物的合成、表征和光物理性质，其中吡啶基残基要么是环金属化螯合配体(1)的一部分，要么作为单齿配体结合到BiIII离子(2)上。这两种配合物在77 K时都是双发射的。对于配合物2，在脱气的CH2Cl2中，芘基磷光持续存在，尽管强度降低。这使得仅有的几个铋复合体之一显示出了这种特性。

Room-temperature phosphorescence and static excimer excitation of pyrene-modified (NCN) pincer bismuth complexes†

We present the synthesis, characterization, and photophysical properties of two pyrene-modified (NCN) pincer bismuth complexes, where the pyrenyl residues are either part of the cyclometalating pincer ligand (1) or bound as monodentate ligands to the Bi^III ion (2). Both complexes are dually emissive at 77 K. For complex 2, pyrenyl phosphorescence persists at r.t. in degassed CH₂Cl₂, albeit with reduced intensity. This renders 2 one of only a handful of Bi complexes showing this property.
