A pyrimidine derived Schiff base chemosensor 2,6-bis-[(4,6-dimethyl-pyrimidin-2-yl)-hydrazonomethyl]-4-methyl-phenol (HL) has been synthesized and characterized [synthesized by single step condensation of 2,6-diformyl-4-methyl-phenol and (4,6-dimethyl-pyrimidin-2-yl)-hydrazine in methanol] for the detection of Al+3 ion in organo-aqueous medium. Compound HL is pale yellow coloured solid, weak fluorescent compound that offered potentiality for chemical sensing of Al+3. Investigation of the fluorescence behaviour of the compound has been carried out in DMSO: H2O (8:2, v/v) solution under biologically relevant conditions in HEPES buffer (pH= 7.4) displayed a significant response to Al+3 as a result of chelation-induced enhanced fluorescence (CHEF). Rigorous experimental studies conclude that title compound (HL) is analytically potential to detect Al+3 in solution with high sensitivity and selectivity having a detection limit of 2.4239 µM.
