一般描述
1′,3′-二氢-1′,3′,3′-三甲基-6-硝基螺（2 H -1-苯并吡喃-2,2′-(2 H )-吲哚）（硝基化合物）是一种光致变色的生物相容螺吡喃分子，在苯并吡喃部分有 6 个硝基。 它有一个无色的无色无色的无色螺环吡喃形式 (SP) 和有色的反式份菁形式 (MC)，分别在紫外和可见光区呈现吸收峰。与其他螺吡喃分子相比，硝基二苯醚具有更高的量子产率，并能溶于多种溶剂。
应用
硝基聚苯硫醚 (NitroBIPS) 是一种光致变色染料，通过静电纺丝可与聚乙烯醇 (PVA) 形成 PVA-螺吡喃纳米纤维。它具有光响应行为，可用于光学数据存储应用。它可以用来掺杂液晶，开发一种双响应的彩色散射装置，并允许电流体力学不稳定性 (EHDI) 的启动。加入 NitroBIPS 可以将透明度从 100% 提高到 16%，提供了屏蔽效果，可用于智能窗口应用。它也可以通过提高剪切强度 7 倍来提高聚苯乙烯 (PS) 在玻璃基板上的粘接性能。
