White light emissive organic fluorophores and halogen atom-controlled tunable and stimuli-induced reversible fluorescence switching

Halogen atom substitution effect on the carbazole fluorescence properties and supramolecular interactions in the solid-state

“…[1][2][3] The molecular structure and supramolecular interaction controlled molecular assembly exerted strong influence on the fluorescence properties in the solid-state. [4][5][6] For instance, polyaromatic π-conjugated molecules showed strong fluorescence in the solution-state but became nonemissive or weakly emissive in the solid-state due to the aggregation caused quenching (ACQ) effect. 7 However, chemical modification such as functional/bulky group substitution prevented the co-facial π⋯π stacking and produced strong fluorescence in solution as well as the solid-state.…”

Single molecule aggregation-induced dual and white-light emissive etherified aroyl-S,N-ketene acetalsviaone-pot synthesis

“…1 Classically, white light emission in devices is generated via a mixture of blue, green and red emitters in the respective active layer of the device. 1 a ,2 With growing interest in white light emission for various applications like OLEDs, 3 in thin films and displays 4 or for molecular sensors and switches, 5 the desire to achieve white light emission from a single emitter molecule steadily increases. 6…”
