摘要

Development of new materials with advanced functionality is a crucial step for future technological innovations.Currently,there is a great demand for more efficient luminescent materials,particularly in the areas of electroluminescence,chemosensor and biotechnology.To respond to this demand,scientists have synthesized a large number of luminescent molecules.Whereas many conventional luminophores are highly emissive in dilute solutions,they become weakly luminescent or non-emissive when aggregated.This luminescence quenching effect has frequently been referred to as aggregation-caused quenching (ACQ).The notorious ACQ problem has prevented many lead luminogens identified by the laboratory solution-screening process from finding real-world applications in an engineering robust form.
