产品说明 一般描述 碘化反式-4- [4-(二甲基氨基)苯乙烯基] -1-甲基吡啶鎓(DASPI)是一种半菁染料。
反式-4-[4-(二甲基氨基)苯乙烯]-1-甲基吡啶碘(DASP)是一种可作为荧光探针的半氰基染料。可通过调节溶液的pH值而对其荧光属性进行调节。它能被光激发以形成能够实现分子间电荷转移态的内捻。 应用 DASP可用来对分子筛晶体的荧光进行表征，从而进一步用于光功能材料的开发。 包装 1 g in glass bottle 基本信息 | 经验(实验)分子式 | C16H19IN2 | | 分子量 | 366.24 | | MDL编号 | MFCD00031907 | | PubChem化学物质编号 | 57648873 |
