materials with optical HOMO–LUMO gaps that were readily tuned by systematic modification of the steric and electronic character of the π-conjugated organic linkers. All five Bi-OMs exhibit completely reversible thermochromism in the solid-state, and possess excellent thermal stability in air up to nearly 300 °C. This combination of physical properties, coupled with the ease of synthesis and the inexpensive
通过以下方法合成了五种可逆热致变色铋基无机-有机杂化材料三苯基铋与四个苯并二硫醇和二烯醇之间的简单一步缩合反应。通过紫外可见光谱和FT-IR光谱,粉末X射线衍射(PXRD),能量色散X射线光谱(EDS),扫描电子显微镜(SEM),元素分析(EA)和热重分析( TGA)。铋有机材料(Bi-OMs)是带有光学HOMO-LUMO间隙的有色材料,可以通过系统地改变π共轭有机连接体的空间和电子特性来对其进行调节。所有五种Bi-OM在固态下均表现出完全可逆的热致变色性,并且在高达接近300°C的空气中具有出色的热稳定性。物理性质的结合,加上易于合成以及铋的廉价,无毒性质,
