The Al 3+ sensor, 7‐nitrobenz‐2‐oxa‐1, 3‐diazole (NBD) derived fluorescent probe 2‐((E)‐(4‐(phenylamino)benzo[c][1,2,5]oxadiazol‐7‐ylimino)methyl) phenol ( 3) was synthesized and characterized by various spectral methods and crystallography. The compound ( 3 ) exhibits dual channel (fluorometric and colorimetric) sensor behaviour. It has high selectivity for Al 3+ detection, produced significant fluorescence enhancement in the presence of Al 3+ ion. It shows ‘‘turn off–on’’ fluorescent responses toward Al 3+ in semi aqueous medium. Here, the correlative the properties of a photo sensor (NBD based schiff‘s base 3 with normal NBD derivatives 1, 2 ) towards Al 3+ was studied. The solvent effect and cation sensing properties were investigated from ultraviolet spectroscopy and fluorescence spectroscopic methods. The facile synthetic probe 3 will alternative and open new opportunities in bio‐imaging of Al 3+ in various cell lines. This will certainly be helpful in understanding the fundamental mechanism of aluminium‐induced human diseases.
