  Aggregation-Induced Emission of Bis(imino)acenaphthene Zinc Complexes: Photophysical Tuning via Methylation of the Flanking Aryl Substituents

  摘要：

  Bis(imino)acenaphthene zinc complexes with methylated aryl substituents have been examined from the standpoint of their photoluminescent properties. Although complexes 1-4 proved to be nonemissive in solution, complexes 1 and 2 were found to emit via an aggregation-induced emission pathway. On the other hand, complexes 3 and 4 were found to be nonemissive in the solid state. Detailed crystallographic studies of complexes 1-4 provided valuable insights into the structural differences between the emissive (1 and 2) and nonemissive complexes (8 and 4), particularly with respect to their molecular Structures and crystal-packing environments. TD-DFT theoretical calculations were carried out and were found to support the hypothesis that the phosphorescent emissions of 1 and 2 are due to the existence of intermolecular pi-stacking interactions within the crystal lattices. Finally, a series of solvatomorphs of complexes 1 and 2 were synthesized and their emissive properties were studied.

  摘要：

  描述了刚性双齿氮配体双-（苯基亚氨基）樟脑（Ph-BIC）和一系列双（芳基））啶（Ar-BIAN）的合成和表征。这些配体是在樟脑醌或苯醌与相应的（取代的）苯胺在ZnCl 2或NiBr 2的存在下反应，然后在随后的步骤中除去金属盐而合成的。NDDO在p Tol- BIAN上的计算表明，该配体的电子性质与开链类似物Ph-DAB（DAB = 1,4-diaza-1,3-butadiene）相当。Ar-BIAN配体的亚胺N原子上的芳族基团定向在双（亚氨基）ac基平面之外，导致形成顺式和反式为异构体的邻位-取代的衍生物ö -MeC 6 ħ 4 -BIAN和OI PRC 6 ħ 4 -BIAN。在溶液中观察到这些配体的一种异构体，但是与Pd（Me）Cl片段配位后，由于形成了两种异构体，因此同时存在顺式和反式形式。此外，描述了尝试合成双（异丙基亚氨基）环己烷，但是发现形成了互变异构的亚胺-烯胺化合物，其

  that are direct precursors to augmented N-heterocyclic carbenes with a fixed cis geometry. Reduction of bis(imino)acenaphthene ligands with a LiAlH4/AlCl3 reagent mix initially produced the corresponding 1,2-diamines which, upon ring-closing reaction with triethyl orthoformate in acidic solution, gave the requisite ionic intermediates. Formation of the carbenes was then shown by preparation of selected

  我们介绍了一种合成苊稠合咪唑啉鎓盐的通用方法，该盐是具有固定顺式几何形状的增强N-杂环卡宾的直接前体。用LiAlH 4 /AlCl 3试剂混合物还原双(亚氨基)苊配体最初产生相应的1,2-二胺，其在酸性溶液中与原甲酸三乙酯发生闭环反应，得到所需的离子中间体。然后通过制备选定的[Cu(NHC)]络合物来显示卡宾的形成，该络合物是通过在Cu(I)源存在下用碱处理相应的咪唑啉鎓盐而获得的。
