A Self-Reporting Approach to Real-Time Monitoring of Dispersion Polymerization for Constructing High-Performance Materials

Dispersion polymerization as the fundamental polymerization methodology has inspired cutting-edge strategies to develop advanced materials for high-tech applications where dynamic processes crucially determine structure and functionality. However, precisely elucidating the dynamic process is highly desirable. Here, we put forward a fluorescence self-reporting strategy for real-time monitoring of dispersion polymerization based on aggregation-induced emission (AIE) and twisted intramolecular charge transfer (TICT). By recording the fluorescence changes of the polymerizable AIE-TICT probe, the microphase separation during the nucleation process is rarely identified, uncovering the entropy-driven propagation of polymer chain experimentally. Remarkably, dynamic hardening processes bearing polymer chain aggregation and polar solvent extrusion are clearly depicted in a self-reporting manner, enriching the traditional understanding of dispersion polymerization. Guided by these, uniform fluorescent polymeric particles are harvested to exhibit their potential in inkjet printing. This finding demonstrates the significant role of the fluorescence-self-reporting approach in understanding microscope processes for constructing high-performance materials.
