In this paper we report a new, simple gelation system based on an acyl hydrazone building block. These gels can be formed by simple mixing of aldehyde and hydrazide followed by a heat/cool cycle, and constitute a simple type of multi-component gel, in which a new covalent bond is formed. Importantly, we demonstrate two different outcomes when this gelation system is challenged with mixtures of different
在本文中,我们报告了一种基于酰基结构单元的新的,简单的凝胶化系统。这些凝胶可以通过将醛和酰肼简单混合,然后进行加热/冷却循环而形成,并且构成简单类型的多组分凝胶,在其中形成新的共价键。重要的是,当这种凝胶体系受到不同醛的混合物的挑战时,我们证明了两种不同的结果-在某些情况下,只有一种醛会与酰肼反应,优先形成有效的凝胶剂并组装成有组织的凝胶,而在其他情况下,两种醛都将与酰肼反应生成共组装体系。通过NMR和差示扫描量热法可以深入了解这些组装过程。
