Supramolecular chemistry of AIE-active tetraphenylethylene luminophores

This book chapter provides recent progress in the development of chemistry of aggregation-induced emission (AIE)-active tetraphenylethylene luminophores, their synthetic strategies, and their applications in the research fields of optoelectronics, sensing and supramolecular science comprehensively. It begins with a discussion on a collection of synthetic structural motifs. We will also explore novel derivatives, structures, electronic and spectroscopic properties of the TPE luminophores. The practical applications include certain topics in medicinal, sensing, optoelectronic devices and supramolecular architectures. We have illustrated advances in tetraphenylethylene research in the mechanoluminescent materials followed by exploring recent development of functionalization/decoration of AIE-active tetraphenylethylene luminogens onto an aggregation-caused quenching (ACQ) fluorophores, such as PDI, NDI and porphyrins, converting the whole chromophore into AIE luminogens with possible applications.
