The structures of two lamellar silver thiolate coordination polymers [Ag( p-SPhCOH)] (1) and [Ag( p-SPhCOMe)] (2) are described for the first time. Their inorganic part is composed of distorted AgS honeycomb networks separated by noninterpenetrated thiolate ligands. The main difference between the two compounds arises from dimeric hydrogen bonds present for the carboxylic acids. Indepth photophysical studies show that the silver thiolates exhibit multiemission properties, implying luminescence thermochromism. More interestingly, the synthesis of a heterometallic lamellar compound, [AgCu( p-SPhCOH)] (3), allows to obtain mixed metal thiolate coordination polymers and to tune the photophysical properties with the excitation wavelengths from a green vibronic luminescence to a single red emission band.
首次描述了两种层状硫醇银配位聚合物[Ag(p - SPhCOH)] (1)和[Ag(p - SPhCOMe)] (2)的结构。它们的无机部分由扭曲的AgS蜂窝网络组成，这些网络被非互穿的硫醇盐配体隔开。这两种化合物之间的主要差异源于羧酸存在的二聚体氢键。深入的光物理研究表明，硫醇银表现出多发射特性，这意味着发光热致变色。更有趣的是，合成一种异金属层状化合物[AgCu(p - SPhCOH)] (3)，可以得到混合金属硫醇盐配位聚合物，并通过激发波长从绿色振动发光调谐到单一红色发射带来调节光物理性质。
