Two iodoargentate hybrids, {[HNOM][AgI]·HO} (1) and {[HINOM][AgI]·HO} (2) (HNOM = N-protonated 3-carbomethoxypyridinium; HINOM = N-protonated 4-carbomethoxypyridinium), have been designed and prepared, which were constructed from typical [AgI] inorganic chains and cationic hydrogen-bonding supramolecular networks (one-dimensional for 1 and three-dimensional for 2) of lattice water and positional isomeric N-protonated carbomethoxypyridinium. Two hybrids exhibit sensitive photochromism based on intermolecular electron transfer (ET) and thermochromism due to reversible hydration and dehydration and the consequent variation of intermolecular charge transfer (CT). Furthermore, loss of lattice water gives rise to improved photochromic dehydrated form 1T and optically inert dehydrated form 2T, suggesting a delicate modulating effect of lattice contraction on the intermolecular CT and ET as well as consequently photoresponsive behaviors.
两种碘银酸盐杂化物，{[HNOM][AgI]·HO}（1）和{[HINOM][AgI]·HO}（2）（HNOM = N-质子化 3-羧甲氧基吡啶鎓；HINOM = N-质子化 4-羧甲氧基吡啶鎓），已被设计和制备，它们由典型的[AgI]无机链和阳离子氢键超分子网络（一维的 1 和三维的 2）组成，由晶格水和位置异构的 N-质子化羧甲氧基吡啶鎓组成。两种杂化物由于分子间电子转移（ET）和由于可逆水合和脱水以及随之而来的分子间电荷转移（CT）的变化而表现出敏感的光致变色和热致变色。此外，晶格水的损失导致光致变色脱水形式 1T 和光学惰性脱水形式 2T 的产生，这表明晶格收缩对分子间 CT 和 ET 以及光响应行为具有精细的调节作用。
