The development of a robust folded scaffold as a fluorescent material using butylidine-linked pyridazinone-based systems <i>via</i> aromatic π⋯π stacking interactions

Abstract

Fluorescence-capable robust folded pyridazinone-based homo- and heterodimers linked with butylidine linkers, whose crystals exhibit fluorescence with quantum yields of 11% (1CN) and 28% (2CN) due to intramolecular stacking, were synthesized.
