Two iodoargentate hybrids, {[HNOM][AgI2]·H2O} (1) and {[HINOM][AgI2]·H2O} (2) (HNOM+ = N-protonated 3-carbomethoxypyridinium; HINOM+ = N-protonated 4-carbomethoxypyridinium), have been designed and prepared, which were constructed from typical [AgI2]− 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.

N质子化碳甲氧基吡啶鎓碘代杂化物的晶格水控光致变色
两个碘代Argantate杂种，{[HNOM] [AgI 2 ]·H 2 O}（1）和{[HINOM] [AgI 2 ]·H 2 O}（2）（HNOM + = N-质子化的3-碳甲氧基吡啶鎓； HINOM + = ñ -protonated 4- carbomethoxypyridinium），已经被设计和制备，这是从典型[碘化银构成2 ] -无机链和阳离子氢键超分子网络（一维为1和三维为2的晶格水）和位置异构体N质子化的碳甲氧基吡啶鎓。两种杂化物由于分子间电子转移（ET）和热致变色而表现出敏感的光致变色性，这归因于可逆的水合和脱水作用以及随之而来的分子间电荷转移（CT）的变化。此外，晶格水的损失导致改进的光致变色脱水形式1T和光学惰性的脱水形式2T，表明晶格收缩对分子间CT和ET的微妙调节作用以及因此引起的光响应行为。
