Tuning solvatochromism and F– sensing via acceptor stoichiometry-mediated charge-transfer modulation in triarylboron-indolocarbazole systems

Key Points

• The aim is to explore how charge transfer affects solvatochromism in triarylboron-indolocarbazole systems.
• Altered triarylboron acceptor stoichiometry on indolocarbazole scaffolds to create two emitters.
• Comparison of single-acceptor and dual-acceptor emitter designs.
• Identified changes in solvatochromism connected to acceptor stoichiometry.
• D-A emitter designs exhibit modulated charge-transfer characteristics.
