Stimuli-responsive systems are an emerging class of materials in fields as diverse as electronics, optoelectronics, cancer detection, drug delivery, or sensing. Especially focusing on nanomaterials, 2D transition metal dichalcogenides have recently attracted the scientific community's attention due to their remarkable intrinsic stimuli-responsive behaviour upon external stimuli such as pH, light, voltage, or certain pathogens. This significant response can be further enhanced by forming mixed-dimensional heterostructures and by molecular functionalization, capitalizing on chemistry to manipulate and boost their intrinsic stimuli-responsive properties. Furthermore, thanks to the endless possibilities of chemistry, a new class of smart materials based on the combination of stimuli-responsive molecular systems with transition metal dichalcogenides has recently been synthesized. In these materials, the physical properties of the 2D layers are reversibly modified by the switchable molecules, not only enhancing their stimuli-responsive behaviour but also providing memory to the hybrid. Therefore, this review explores the recent breakthroughs in the chemical design of smart transition metal dichalcogenides with built-in responsiveness.
刺激响应系统是一类新兴材料，广泛应用于电子、光电子、癌症检测、药物递送或传感等领域。特别是对于纳米材料，二维过渡金属二硫属化物由于其在pH值、光、电压或某些病原体等外部刺激下具有显著的固有刺激响应行为，最近引起了科学界的关注。通过形成混合维度异质结构和分子功能化，利用化学方法来操纵和增强其固有刺激响应特性，可以进一步增强这种显著的响应。此外，由于化学具有无限的可能性，最近合成了一类基于刺激响应分子系统与过渡金属二硫属化物相结合的新型智能材料。在这些材料中，二维层的物理性质可通过可切换分子进行可逆修饰，这不仅增强了它们的刺激响应行为，还为这种复合材料提供了记忆功能。因此，本综述探讨了具有内置响应性的智能过渡金属二硫属化物化学设计方面的最新突破。
