interaction and luminescent properties of a gold(I) carbene complex. The Au(I) complex [(L)Au(I)Cl] (1), where L = N-(9-anthracenyl)-N′-(heptyl)benzimidazol-2-ylidene, was prepared, and thermal, emission, and lifetime properties along with a density functional theory study have been considered. X-ray diffraction analysis of single crystals evidenced the solid-state structure of gold complex 1, which exhibited
我们提出了一种罕见的分子内Au···H–C(sp 3)氢键相互作用和金(I)卡宾配合物的发光性质。制备Au(I)配合物[(L)Au(I)Cl](1),其中L = N-(9-蒽基)-N' -(庚基)苯并咪唑-2-亚基,并进行热发射,并考虑了寿命特性以及密度泛函理论研究。单晶的X射线衍射分析证明了金配合物1的固态结构,其显示出预期的线性配位几何形状。L的正庚烷臂调节Au(I)和CH 2部分之一的氢原子之间的氢键相互作用。由于分子间Cl···H相互作用,金(I)卡宾配合物的堆积在固态显示出有趣的一维柱状。尝试将400-560 nm区域中1的蓝色发射归因于配体和金的跃迁,但氢键相互作用也可能有部分贡献。
