synthesized photoluminescent organic acceptor, 5,10-dimethyl-5,10-diaza[5]helicene is shown to react with dicyanoaurate anions to form a 2D network N,N-dimethylaza[5]helicene dicyanoaurate. The structure of the synthesized complex was investigated via X-ray crystallography showing the presence of [Au(CN)2]− dimers and monomers within the helicene framework. Photophysical measurements between 298 K and 10 K indicate
显示了最近合成的光致发光有机受体5,10-二甲基-5,10-二氮杂[5]螺旋与二氰基金酸酯阴离子反应形成二维网络N,N-二甲基氮杂[5]螺旋二氰基金酸酯。通过X射线晶体学研究合成的配合物的结构,显示出在螺旋烯骨架内存在[Au(CN)2 ] -二聚体和单体。298 K和10 K之间的光物理测量表明,[Au(CN)2 ] -阴离子被5,10-二甲基-5,10-二氮杂[5] ic烯通过电子转移。Stern-Volmer和Rehm-Weller分析表明,这是由于电子从[Au(CN)2 ] -阴离子转移到5,10-二甲基-5,10-二氮杂[5]螺旋烯而猝灭的结果。共振能量转移。进行DFT计算以支持电子转移的分配。
