一系列含有两个3，5-二甲基吡唑单元连接到中心荧光萘基间隔基的配体已被用于制备Ag（I）网络，其结构已被表征。Ag（I）离子耐受广泛配位环境的能力导致形成三种不同的结构类型：线性一维链、二维片和三维网络。在络合时，配体排列以使配体间芳族π-堆积相互作用最大化，结果是许多所得化合物显示出固态低能激基复合物发射特征，远远超出正常萘发射范围。
A series of ligands containing two 3,5-dimethylpyrazole units connected to a central fluorescent naphthyl spacer have been used to prepare Ag(I) networks which have been structurally characterised. The ability of Ag(I) ions to tolerate a wide range of coordination environments has resulted in the formation of three different structural types: linear one-dimensional chains, two-dimensional sheets and three-dimensional networks. Upon complexation the ligands arrange so as to maximise inter-ligand aromatic π-stacking interactions, with the consequence that many of the resulting compounds display in the solid-state low-energy exciplex emission features extending well beyond the normal naphthalene emission range.
