一种材料的弱点，尤其是受到化学、机械或物理刺激时，通常被视为极其负面的东西。有无数的例子表明，看起来很有趣的材料因为太不稳定而被驳回。但刺激方案的不稳定性并不总是负面的。在这个视角中，我们强调了材料的弱点可以作为合成工具来制备材料的情况，目前，使用传统的合成方法很难甚至不可能制备材料。为了强调这个概念，我们将借鉴纳米多孔材料领域的例子，集中在金属有机框架和沸石上，但一般概念可能适用于广泛的材料化学。在沸石化学中，有一个特殊的问题，即获取这种方法可能解决的假设结构。
Weakness in a material, especially when challenged by chemical, mechanical or physical stimuli, is often viewed as something extremely negative. There are countless examples in which interesting-looking materials have been dismissed as being too unstable for an application. But instability with respect to a stimulus is not always a negative point. In this Perspective we highlight situations where weakness in a material can be used as a synthetic tool to prepare materials that, at present, are difficult or even impossible to prepare using traditional synthetic approaches. To emphasize the concept, we will draw upon examples in the field of nanoporous materials, concentrating on metal-organic frameworks and zeolites, but the general concepts are likely to be applicable across a wide range of materials chemistry. In zeolite chemistry, there is a particular problem with accessing hypothetical structures that this approach may solve.
