摘要: 设计合成了9,10-二(N-甲基吩噻嗪-3-乙烯基)蒽(PT-C1)化合物,通过一系列 的测试证明该化合物PT-C1具有聚集诱导荧光增强(AIE)和压致荧光变色(PEC)的现象。化合物 PT-C1的AIE 现象是由于随着水含量的增加化合物从溶液中的分散状态变成了纳米聚集状态使其扭摆运动受到了限制。XRD和DSC的测试证明引起化合物产生压致荧光变色的原因是化合物在研磨的过程中发生了由晶态到无定型态转变。

Abstract: We synthetized a conjugated organic molecule (PT-C1) and found that the compound has strong aggregation induced emission(AIE) effect and piezofluorochromism(PFC) effect. With the increase of water fraction,which has strong AIE effect. The reation is that the state of aggregation turns into nanoaggregation that restricts intramolecular rotation. XRD and DSC analyses indicate that grinding and annealing could induce the phase transition of the PT-C1 solid between crystalline and amorphous states, which should be responsible for the PFC behavior.
Key words: anthracene-centered; aggregation-induced emission; piezofluorochromic
