Abstract

We report a luminescent anthracene-guanidine derivative that forms rare T-shape dimers, resulting in an excimer with a quantum yield approaching one. Water plays a fundamental role through H-bonding guiding the self-assembly. These results establish a new framework for environmentally friendly aggregation-induced emission luminogens.
