title: N-type pyrazine and triazole-based luminogens with aggregation-enhanced emission characteristics.
abstract: N-type pyrazine-based 1,4- and 1,5-disubstituted 1,2,3-triazole derivatives, showing unique aggregation-enhanced emission characteristics, were facilely prepared via Cu- and Ru-catalysed azide-alkyne cycloadditions, respectively. Thanks to their electron-deficient properties, they could readily form red-emissive charge transfer complexes with electron-donating triphenylamine in the aggregate and solid states.
