Modulation of Solid-state Luminescence Quantum Efficiency Based on CH–O Intermolecular Interaction

Solid-state luminescence quantum efficiency is modulated drastically by CH–O interaction and packing rigidity of secondary ammonium anthracene-2,6-disulfonate. Appropriate alkyl chains of amines gave small free space and long CH–O distance, resulting in strong luminescence due to suppression of nonr...

Zusammenfassung:Solid-state luminescence quantum efficiency is modulated drastically by CH–O interaction and packing rigidity of secondary ammonium anthracene-2,6-disulfonate. Appropriate alkyl chains of amines gave small free space and long CH–O distance, resulting in strong luminescence due to suppression of nonradiative decay. This is the first demonstration that CH–O intermolecular interaction has great influence on solid-state luminescence quantum efficiency.
