The roles of packing modes in manipulating gel stability and luminescence behavior in fluorescent supramolecular gels

Fluorescent supramolecular gel is a large group in luminescent gels. In the scope of practical applications, excellent stability and robust luminescence are complementary and indispensable for high-performance fluorescent supramolecular gels. Therefore, in this Perspective, the proceedings of precursor explorations of stabilizing and boosting the luminescence behavior of the gels will be briefly summarized. The challenges and possible development frontiers will also be pondered to inspire future scientific research achievements.
