Abstract

Aggregation-induced emission (AIE) is a unique and abnormal fluorescence phenomenon that has attracted increasing research interest over the past decades. Since its discovery in 2001, many AIE-active molecules with different structure, functional groups and optical properties have been reported. These AIE-active molecules can be further utilized to fabricate various functional materials, which have exhibited great potential for different applications ^[1].

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

The recently developed vortex fluidic device (VFD) is a relatively inexpensive research tool for controlling chemical reactivity and selectivity, materials synthesis and probing the structure of self-organized systems, offering a range of benefits over conventional processing ^[5]. Here, a few case studies will also be talked to demonstrate the innovation of combining AIE and VFD together to form AIE hydrogels as well ^[6-8]

This significant strategy in functionalised materials with AIE features has the potential for developing more efficient techniques for characterizing advanced nanomaterials and understanding biological processes and detection methodologies.

Bio:

Dr Youhong Tang is a Professor and was an Australian Research Council-Discovery Early Career Researcher (ARC-DECRA) in Flinders University. Currently, he is the Deputy Director of International Laboratory for Health Technologies and Deputy Director of ACSRF-Joint Research Centre on Personal Health Technologies, a research leader in Institute for Nano Scale Science and Technology (ERA rank 5 in nanotechnology) and Medical Device Research Institute (ERA rank 5 in materials engineering) in Flinders University, Australia. He was elected as a Project Management Professional of Project Management Institute (PMI), US in 2008, a Fellow of Royal Society of Chemistry (FRSC), UK in 2018 and a Fellow of the Royal Australian Chemical Institute (FRACI), Australia in 2021.

Dr Tang obtained his PhD degree in the Hong Kong University of Science and Technology in 2007 and moved to Flinders University in 2012 from the University of Sydney. He is a material science and engineering researcher with research interests mainly focused on (1) Structure-processing-property relationship of polymeric (nano)materials; (2) Biomaterials, biosensors and their devices with aggregation-induced emission features.
