Gold thiolate coordination polymers (CPs) are anisotropic materials with 1D or 2D networks exhibiting a large palette of photoluminescence properties. In this paper, we show that, from both lamellar acid and ester, [Au(p-SPhCO₂X)]_n CPs (X = H, Me), it is possible to perform post-synthesis esterification or saponification reactions. Three new 2D phases with X = Na, K and Cs were isolated. In addition, ligand exchange reactions were carried out from 1D [Au(p-SPh)]_n CP and 2D [Au(p-SPhCO₂X)]_n CPs (X = H, Me) and the transformations from 1D to 2D structures and vice versa point out a mechanism of dissolution and recrystallization that is governed by the nature of the ligands and the presence of weak interactions. The obtained compounds exhibit solid state and RT photoemission characteristic of their structure.

基于苯硫醇金（I）的配位聚合物中的合成后官能化和配体交换反应

硫醇金配位聚合物（CPs）是具有一维或二维网络的各向异性材料，具有大的光致发光特性。在本文中，我们表明，从层状酸和酯中，[Au（p -SPhCO ₂ X）] _n CPs（X = H，Me）均可进行合成后的酯化或皂化反应。分离出三个新的二维相，分别为X = Na，K和Cs。此外，从1D [Au（p -SPh）] _n CP和2D [Au（p- SPhCO ₂ X）] _n CP（X = H，Me）进行配体交换反应，并从1D转换为2D结构和反之亦然指出了溶解和重结晶的机制，该机制受配体的性质和弱相互作用的存在支配。所获得的化合物显示出其结构的固态和RT光发射特性。
