Molecular and supramolecular room temperature phosphorescences from metal free carbonyl functionalized triazinic scaffold
Key Points
Long-lived phosphorescence was observed in cyclic triimidazoles with benzaldehyde substituents, indicating molecular aggregation effects.
These materials demonstrate unique properties of room temperature phosphorescence due to CO–π and π–π interactions.
Assessment involved crystalline states of compounds revealing molecular and aggregate origin of the phosphorescent features.
Understanding these phosphorescent systems may lead to innovative applications in optoelectronic devices.
Abstract
Cyclic triimidazoles endowed with one or three benzaldehyde substituent(s) display in their crystalline state only long-lived features of molecular and aggregate (CO–π and π–π) origin.
