About this collection
A themed collection on aggregation-induced emission (AIE) featuring articles specially selected by Professor Bin Liu, National University of Singapore, and Professor Ben Zhong Tang, Hong Kong University of Science and Technology.
AIE research has now drawn extensive attention and AIE luminogens (AIEgens) have been recognized as a novel type of advanced functional material with high-tech applications. This innovative concept has significantly changed the understanding of the scientific community toward classic photophysical phenomena and put forth a revolution of luminogenic materials research, both conceptually and technically. AIEgens show unique advantages such as high photostability, high brightness, large Stokes shift, and good biocompatibility, which provide a fantastic platform for the development of a wide spectrum of applications.
This themed collection showcases articles from deciphering the fundamental working mechanism, developing new AIE systems, to exploring applications in organic optoelectronic devices, chemical sensing, bioimaging and theranostics. An in-depth perspective on challenges and opportunities in AIE research is also presented.
