The Design and Research of a Topological Multi-Functional Mechanophore

Abstract

从探索新的化学理论到开发新型力响应聚合物材料,力化学特别是高分子力化学学科的飞速发展受到了广泛的关注。力色团是高分子力化学的核心,是一类在机械力的作用下能够发生特异性反应的活性基团。至今,已报道的力色团有数十种,有变色、发光、催化、释放小分子等响应方式,但大多数功能单一,不能满足力响应材料的设计与合成。 本文工作提出了一种将已有力色团重新排列组合从而制备多功能性复合力色团的合成方法。防护(Gated)力色团就是在目标力色团的前端嵌入一个保护性的力色团,要使得机械力传导到目标力色团并活化,保护力色团必须先被活化。这样的好处是可以延缓目标力色团响应性的表达,起到保护的作用,这为某些需要保护的基团...In the recent years, the explosion of polymer mechanochemistry attracted more and more researcher’s attention who were devoted on the development and application. The key problem is the innovation of mechanophores that can react under the mechanical force and result in the predictable response. Up to now, several dozens of mechanophores had been explored. But it can’t meet experts needs because o...学位:理学硕士院系专业:化学化工学院_高分子化学与物理学号:2052013115165
