A sodalite material with a composition of Na₈[Al₆Si₆O₂₄](I,S)₂ was synthesized from zeolite A via a hydrothermal reaction of a mixed solution of sodium iodide and sodium sulfide. The stoichiometric amount of NaI required to synthesize iodide sodalite (Na₈[Al₆Si₆O₂₄]I₂) from zeolite A (Na₁₂[Al₁₂Si₁₂O₄₈]) was defined as a NaI content of 1.0, and synthesis was carried out using a NaI content of 0–25. The color of the obtained samples was almost white; however, the samples became blue or yellow following calcination. The blue color, which was attributed to the formation of S₃⁻ color centers similar to those in ultramarine, was obtained after calcination at 700–800 °C. However, samples calcined at 900 and 1000 °C were yellow. Raman spectroscopic analysis revealed that the formation of I₂ molecules induced the color change to yellow. Among the prepared specimens, the yellow specimen prepared at 7.5 times the stoichiometric ratio of NaI exhibited the largest b* value in the CIELAB color space, which represents the blue–yellow component, with blue in the negative direction and yellow in the positive direction. No proportional relation was observed between the b* values and the amount of NaI added, suggesting that an appropriate I/S ratio existed for yellow coloration in sodalite. The yellow sample exhibited thermochromism with the absorption band broadening toward longer wavelengths and reddening at higher temperatures. This material has not been previously reported and is expected to have applications as a new host–guest material.

以沸石A为原料，通过碘化钠和硫化钠混合溶液的水热反应合成了Na ₈ [Al ₆ Si ₆ O ₂₄ ](I,S) _{2的方钠石材料。}从沸石 A (Na ₁₂ [ Al ₁₂ Si ₁₂ O _{48 ) 合成碘化方钠石 (Na 8} [Al ₆ Si ₆ O ₂₄ ]I _{2 )}所需的 NaI 化学计量量]) 被定义为 1.0 的 NaI 含量，并且使用 0-25 的 NaI 含量进行合成。所得样品颜色接近白色；然而，样品在煅烧后变成蓝色或黄色。在 700–800 °C 下煅烧后获得蓝色，这归因于类似于群青的S ₃ ^{-色心的形成。}然而，在 900 和 1000 °C 下煅烧的样品是黄色的。_{拉曼光谱分析表明，I 2}的形成分子诱导颜色变为黄色。在制备的样品中，以 7.5 倍 NaI 化学计量比制备的黄色样品在 CIELAB 颜色空间中表现出最大的 b* 值，代表蓝-黄色成分，负方向为蓝色，正方向为黄色。在 b* 值和添加的 NaI 量之间没有观察到比例关系，这表明方钠石中的黄色着色存在适当的 I/S 比。黄色样品表现出热致变色现象，吸收带向更长的波长变宽，并在较高温度下变红。这种材料以前没有被报道过，并且有望作为一种新的主​​客体材料得到应用。
