Dissipative self-assembly is a chemical process ubiquitous in and essential to living systems. Its dynamic nature makes it quite appealing to directly visualize and monitor in real-time, thus facilitating the understanding of this phenomenon. Herein, we have demonstrated for the first time a dissipative self-assembling system that in situ exhibits intrinsic fluorescence only in the assembly state by the employment of AIEgens, enabling its direct visualization and real-time monitoring using fluorescence microscopy and spectroscopy, respectively. Fluorescence assay, as a non-invasive and real-time monitoring technique with high sensitivity and resolution, represents a privileged way to disclose the kinetics of dissipative systems, which is on demand on account of their dynamic feature. Furthermore, transient Förster resonance energy transfer was validated as a proof-of-principle function and also to afford dual-channel monitoring.

通过同步耦合聚集诱导的发射，直接可视化并实时监控耗散自组装

耗散自组装是生命系统中普遍存在且必不可少的化学过程。它的动态特性使直接可视化和实时监视变得非常吸引人，从而促进了对该现象的理解。在这里，我们首次展示了一种原位耗散的自组装系统通过使用AIEgens，仅在组装状态下才能显示固有的荧光，从而可以分别使用荧光显微镜和光谱法对其进行直接可视化和实时监控。荧光测定法作为一种具有高灵敏度和分辨率的非侵入性实时监测技术，是揭示耗散系统动力学的一种特权方式，由于其动态特性，这是必不可少的。此外，瞬态Förster共振能量转移已被验证为原理证明功能，并且还提供了双通道监测。
