Self-agglomerated crystalline needles harnessing ESIPT and AIEE features for the ‘turn-on’ fluorescence detection of Al 3+ ions
We report the synthesis of probe 2 for the fluorescence “turn-on” detection of Al 3+ ions in CH 3 OH. Probe 2 has been designed via utilizing the aggregation-induced emission properties of the tetraphenylethylene unit, with further enhancement from Schiff base units for the ESIPT phenomenon. Probe 2...

has been designed
via
utilizing the aggregation-induced emission properties of the tetraphenylethylene unit, with further enhancement from Schiff base units for the ESIPT phenomenon. Probe
2
exhibits emission at 548 nm (
λ

= 360 nm), with a large Stokes shift of 188 nm, indicating the ESIPT phenomenon. Probe

also exhibits emission enhancement
via
increasing the H

O/THF (v/v) and altering the spherical morphology to needle shapes. Probe
2
has been found to be highly selective and sensitive towards Al
3+
ions over other metal ions in pure CH

OH using absorption and emission spectroscopy. FESEM analysis revealed that the size of probe
2
increases upon the addition of Al

ions. Thus, the fluorescence “
