Acid resistance (12 M HCl) was made possible for two isomorphic two-dimensional silver-based coordination polymers. Protection is provided by a hydrophobic organic shell and a dynamic proton buffer layer via a thiolate-thione tautomerism of 2-thiobenzimidazole ligands. Thus, these ligands are promising surface inhibitors, acting as a dual protective shield against metal corrosion.

层状银配位聚合物中的超稳定抗酸“屏蔽”

两种同构二维银基配位聚合物具有耐酸性（12 M HCl）。疏水性有机壳和动态质子缓冲层通过 2-硫代苯并咪唑配体的硫醇盐-硫酮互变异构提供保护。因此，这些配体是有前途的表面抑制剂，可作为金属腐蚀的双重保护屏障。
