[Au(C6F5)(Tht)]与1，3，5-三氮-7-磷杂金刚烷和3，7-diacetyl-1，3，7-triaza-5-phosphabicyclo[3.3.1]nonane反应生成[Au(C6F5)(PhOSPH)](PHOSPH=PTA，1；PHOSPH=DAPTA，2)。该化合物在较高浓度下微溶于水和聚集体，导致形成针状和棒状结构(1)和组织良好的球形聚集体(2)。X-射线晶体结构测定表明，化合物1和2均与AgPF6反应生成1：1Au···Ag异金属发光配合物。使用在反离子上不同的不同银盐会导致结果发光和聚集形态的变化。
The reaction of [Au(C6F5)(tht)] (tht = tetrahydrothiophene) with 1,3,5-triaza-7-phosphaadamantane (PTA) and 3,7-diacetyl-1,3,7-triaza-5-phosphabicyclo[3.3.1]nonane (DAPTA) leads to the formation of [Au(C6F5)(phosph)] (phosph = PTA, 1; phosph = DAPTA, 2). The compounds are slightly soluble in water and aggregate at higher concentrations, giving rise to the formation of needle- and rodlike structures (1) and well-organized spherical aggregates (2). Compounds 1 and 2 were reacted with AgPF6, giving rise to the formation in all cases of luminescent water-soluble 1:1 Au···Ag heterometallic complexes, as evidenced by X-ray crystal structure determination. The use of different silver salts that differ on the counterion induces changes in the resulting luminescence and aggregation morphology.
