一般說明

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。

應用

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。

Graphene has emerged as the new wonder material. Being only one atom thick and composed of carbon atoms arranged in a hexagonal honeycomb lattice structure, the interest in this material has exploded exponentially since 2004 when it was first isolated and identified using a very simple method.
