Abstract

Aggregation-induced emission (AIE) isa unique and abnormal fluorescence phenomenon that has attracted increasingresearch interest over the past decades. Since its discovery in 2001, manyAIE-active molecules with different structure, functional groups and opticalproperties have been reported. These AIE-active molecules can be furtherutilized to fabricate various functional materials, which have exhibited greatpotential for different applications [1].

The functionalmaterials with AIEgen inside created a unique research direction in both functionalmaterials and AIE research communities. In this talk, the progress of combiningpolymers with AIEgens to form functional materials has been updated, especiallytheir applications for visualization, monitoring, sensing and detecting havebeen emphasized. A few case studies in our group for AIE hydrogels inbiomedical applications have been highlighted [2-4].

The recently developed vortex fluidicdevice (VFD) is a relatively inexpensive research tool for controlling chemicalreactivity and selectivity, materials synthesis and probing the structure ofself-organized systems, offering a range of benefits over conventionalprocessing [5]. Here, a few case studies will also be talked todemonstrate the innovation of combining AIE and VFD together to form AIEhydrogels as well [6-8]

Thissignificant strategy in functionalised materials with AIE features has thepotential for developing more efficient techniques for characterizing advancednanomaterials and understanding biological processes and detection methodologies.
