A series of dimethyl (linear), tetramethyl (V-shape) and hexamethyl (star like) substituted triphenyl amine derivatives were synthesized and studied their photo physical properties and aggregation induced emission.
All the TPA derivatives were sensing for efficient and fast detection of picric acid.
From the photophysical studies, all the TPA derivatives were strongly concentration dependent aggregation by π- π interaction and also in the solution state fluorescence study revealed that all the compounds have very binding affinity for picrate anion.
