Three gold(i) tripodal complexes containing the tris(2-pyridylmethyl)amine (TPA) ligand coordinated to Au-PR moieties (PR = 1,3,5-triaza-7-phosphatricyclo[3.3.1.13.7]decane, PTA (1), 3,7-diacetyl-1,3,7-triaza-5-phosphabicyclo[3.3.1]nonane, DAPTA (2) and triphenylphosphane (3)) were prepared together with a cage-like structure containing triphosphane 1,1,1-tris(diphenylphosphinomethyl)ethane (4). The luminescence of these complexes has been studied and they show a red shift upon the formation of heterometallic complexes by reaction with Zn(NO), CuCl and [Cu(CHCN)]BF. The different coordination motifs of the Zn and Cu heterometallic species and the resulting changes in the recorded absorption, emission and NMR spectra were analysed and supported by TD-DFT calculations.
制备了三种含三（2-吡啶甲基）胺（TPA）配体且与金-膦配体（PR = 1,3,5-三氮杂-7-磷杂三环[3.3.1.13.7]癸烷，即PTA（1）、3,7-二乙酰基-1,3,7-三氮杂-5-磷杂双环[3.3.1]壬烷，即DAPTA（2）和三苯基膦（3））配位的金（I）三脚架配合物，以及一种含三膦1,1,1-三（二苯基膦基甲基）乙烷（4）的笼状结构。研究了这些配合物的发光性质，并且它们在与硝酸锌、氯化铜和[Cu(CHCN)₄]BF反应形成异金属配合物时会出现红移。分析了锌和铜异金属物种的不同配位模式以及记录的吸收、发射和核磁共振光谱中产生的变化，并通过含时密度泛函理论（TD-DFT）计算加以支持。
