Abstract
Benzophenone azine based schiff base exhibiting AIE and ESIPT phenomenon has been synthesised and studied the photophysical behaviour towards detection of Al3+ ions. The results showed that compound 2 exhibit feeble excited state intramolecular proton transfer emission in CH3CN and undergo aggregation induced emission in >70% H2O-CH3CN. The compound 2 shows significant hydrodynamic diameter change from 20 nm to 200 nm upon increasing the H2O volume ratio in CH3CN. Compound 2 shows colorimetric and “off-on” emission response for Al3+, with detection limit of 2.7 × 10−7 M in CH3OH. The association of compound 2 to Al3+ also causes restriction in intramolecular motion induced emission. The hydrodynamic diameter of compound 2 increases from 335 nm to 625 nm in the presence of Al3+ ion in CH3OH.
