Aminopyridine oligomers exhibited long-lived emission at 77 K, which could be assigned to the delayed fluorescence. The macrocyclic structure predominantly dictated the emission behaviors. Their emission behaviors were elucidated from time-dependent density functional theory calculations.
氨基吡啶低聚物在 77 K 时表现出长寿命发射,这可归因于延迟荧光。大环结构在很大程度上决定了其发射行为。我们通过与时间相关的密度泛函理论计算阐明了它们的发射行为。
Molybdenum(0)‐Tricarbonyl Complex Supported by an Azacalix‐pyridine Ligand: Synthesis, Characterization, Surface Deposition and Conversion to a Molybdenum(VI)‐Trioxo Complex with O2
This study describes the synthesis of a molybdenum(0) tricarbonyl complex supported by an azacalixpyridine ligand. This complex can activate CO and reacts with dioxygen (O2) in solution, in the solid state and on surfaces to form a molybdenum(VI) trioxo complex which mediates O-transfer from dioxygen to external substrates.
本研究描述了氮杂花吡啶配体支持的钼 (0) 三羰基络合物的合成。该络合物可以活化 CO 并与溶液中、固态和表面上的分子氧 (O 2 ) 反应,形成三氧钼 (VI) 络合物,介导 O 从分子氧转移到外部底物。
