Tunable Emission Properties of Indolizine-Based Aggregation-Induced Emission Luminogens for White-Light Emission.

ABSTRACT: Unlike conventional fluorophores experiencing aggregation-caused quenching (ACQ) in the solid state, aggregation-induced emission (AIE) luminogens (AIEgens) exhibit enhanced fluorescence upon aggregation. This property renders AIEgens promising for various technological applications. However, developing red-emitting AIEgens with high fluorescence efficiency remains challenging due to structural constraints. Compact red-light-emitting AIEgens hold great potential, as their small, simple fluorescent frameworks enable facile modification and precise color tuning. This study presents a novel compact indolizine-based AIE system with solid-state emission tunable from cyan (496 nm) to deep red (669 nm), with an average molecular weight (MW) of 312.8 g/mol. The deep-red-emitting derivative is unco
