标题:类似于自然光合作用 Z 方案的基于红光的双光氧化还原策略
摘要:光氧化还原催化通常依赖于使用单个发色团,而将两种不同的光吸收剂组合在一起的策略很少见.在绿色植物的光系统 I 和 Ii 中,两个独立的发色团 P 680和 P 700都相互独立地吸收光,然后它们的激发能量在所谓的 Z 方案中组合,以驱动热力学上的整体反应非常严格.在这里,我们采用这个概念在有机基材上进行光氧化还原反应,其中两个红色光子的组合能量输入而不是蓝色或紫外光.具体来说,Cu I双(α-二亚胺)配合物与原位结合在过量的二异丙基乙胺催化下形成 9,10-二氰基蒽自由基阴离子.50 次脱卤和脱甲苯基反应.这种双重光氧化还原方法似乎很有用,因为红光的破坏性较小,并且比蓝光或紫外线辐射具有更大的穿透深度.紫外-可见瞬态吸收光谱表明,溶剂从乙腈到丙酮的细微变化会引起反应机制的转变,包括主要的光诱导电子转移或主要的三重态-三重态能量转移途径.我们的研究说明了在多光子激发条件下运行的系统的机械复杂

摘要:Herein are disclosed fluorescent dyes based around a framework for a ligand comprising a pyridyl group linked to a diaryl anilido unit. A variety of ligands based on this framework are disclosed. The ligands chelate to a BF 2 center to produce the fluorescent dye. The disclosed dyes combine longer Stokes shifts (approximately 100 nm) with increased quantum yields. They are also photostable in aqueous and organic solutions for several hours. These dyes may be used in the labeling of biomolecules for bioimaging and assays. Also disclosed are methods for the synthesis of these dyes.

摘要:The present invention relates to a green thermally-activated delayed fluorescent material having non-doping properties and a preparation method therefor. The material is 3,5-bis(9H-carbazol-9-yl)-2,4,6-tris(3,6-ditert-butyl-9H-carbazol-9-yl)benzonitrile. The provided compound exhibits a large twist angle between a donor and an acceptor, and is characterized by twisted internal charge transfer (TICT), and by the advantages of having typical thermally activated delayed fluorescence (TADF) properties, a high fluorescence quantum yield (PLQY) of 100%, and a high thermal stability. More importantly, the compound has no aggregate concentration quenching (ACQ) effect when in a pure film state. Additionally, the material has fewer synthesis and preparation steps, readily available raw materials, simple synthesis and purification processes, and high yields, and can be synthesized and prepared on a large scale.
