The development of ultrasmall, luminescent metal nanoclusters (MNCs) with aggregation-induced emission (AIE) characteristics is a relatively new research area that has gained significant attention in various multidisciplinary applications such as optoelectronics, sensing, imaging, and therapy. The numerous scientific breakthroughs in the AIE field provide many tools that, if incorporated into MNCs design strategies, could help realize various new and exciting MNC-based avenues that maximize the utilization of the AIE phenomenon. Indeed, leveraging the aggregation strategies from the AIE community with the judicious use of various covalent and noncovalent interactions has been demonstrated to be effective for constructing several MNC-based hybrid assemblies with enhanced AIE characteristics. In this Perspective, we summarize the key driving forces and routes of MNC assembly together with their impact on deciphering the working mechanism behind the AIE process. These strategies can inspire the design of highly luminescent MNC-based hierarchical functional materials across multiple length scales.

基于聚集诱导发射的高发光金属纳米团簇组装的驱动力和途径

具有聚集诱导发射 (AIE) 特性的超小型发光金属纳米团簇 (MNC) 的开发是一个相对较新的研究领域，在光电子学、传感、成像和治疗等各种多学科应用中引起了极大的关注。AIE 领域的众多科学突破提供了许多工具，如果将这些工具纳入跨国公司的设计策略，可以帮助实现各种新的、令人兴奋的基于跨国公司的途径，最大限度地利用 AIE 现象。事实上，利用 AIE 社区的聚合策略以及明智地使用各种共价和非共价相互作用已被证明对于构建具有增强的 AIE 特性的几种基于 MNC 的混合组件是有效的。在这个视角下，我们总结了 MNC 组装的关键驱动力和路线，以及它们对破译 AIE 过程背后工作机制的影响。这些策略可以激发跨多个长度尺度的高发光基于 MNC 的分层功能材料的设计。
