Aggregation‐induced emission (AIE) stands for an intriguing phenomenon that a series of non‐planar molecules that are nonluminescent or weakly emissive in solutions are induced to emit strongly in the aggregated or solid states. Recently, AIE becomes a very hot research topic as evidenced by the exponential growth of AIE‐related publications and citations. Herein, the recent advances of a class of...
It has been a textbook knowledge that chromophore aggregation generally quenches light emission. Here, we present an opposite phenomenon termed aggregation-induced emission (AIE) and identified the restriction of intramolecular rotation as a main cause for the AIE effect. Based on the mechanistic understanding, we explored the technological applications of the AIE luminogens as light-emitting and...
Fluorescence correlation spectroscopy (FCS) was used to study the nano-clusters of silole molecules formed by aggregation from solutions in acetone-water mixtures. It allowed the determination of the size of clusters in nanometer scale. Aggregate formation was investigated systematically by measuring the cluster sizes made at different silole concentrations and water contents.
