We present a brief review of some important conceptual and practical aspects for the design and properties of molecular luminescent gelators and their gels. Topics considered include structural and dynamic aspects of the gels, including factors important to their ability to emit radiation from electronically excited states.
Keywords: aggregation-induced emission enhancement (AIEE), quantum yield; excimer; fluorescence; gel; luminescence; molecular organic gelator (LMOG), hydrogel; phosphorescence.
