Pt(II)–Pt(II) and π–π interactions. The tuning of the emission properties of the organoplatinum(II) compounds was achieved by changing the direction of hydrogen bonding sites and the molecular scaffold having two 2,6-dihexamidopyridine moieties as a complementary hydrogen bonding site for the uracil moiety, which depends on the regulation of the aggregated structures, to induce the Pt(II)–Pt(II) and
通过将相应的尿嘧啶衍生物和有机铂(II)化合物[4-辛氧基-(C ^ N ^ N)PtCl]偶联来设计生物有机金属铂(II)化合物PtU6和PtU5。PtU6的单晶X射线结构测定揭示了通过两个独立分子的尿嘧啶部分之间的分子间氢键形成二聚体结构,其中每个氢键合的二聚体通过Pt(II)–Pt(II)和π连接。 –π相互作用。有机铂发射特性的调节(Ⅱ))化合物是通过改变氢键合位点的方向和具有两个2,6-二六氨基吡啶吡啶部分作为尿嘧啶部分的互补氢键合位点的分子支架来实现的,这取决于聚集结构的调控,从而诱导Pt(II)–Pt(II)和π–π相互作用。
