title: Determining the critical particle size to induce enhanced emission in aggregates of a highly twisted triarylamine.
abstract: Towards highly luminescent aggregates: A highly twisted triphenylamine displays aggregation-induced enhanced emission. A solvent-specific critical molecular aggregate size, once reached, gives rapid onset of enhanced emission in polar solvent mixtures that favor quenching of solvated individual molecule excited states.
