A new colorimetric and fluorescent chemosensor for Al3+ based on Rhodamine 6G was simply synthesized and investigated for photophysical properties. Rhodamine 6G derivated fluorescent chemosensor(1) was designed and synthersized by imine synthesis of rhodamine 6G ethylenediamine and 8-Hydroxyquinoline-2-carboaldehyde. Chemosensor(1) displayed obvious color change from colorless to pink (under normal light) and non-fluorescent to yellowish-green fluorescent in the Al3+ direction in the acetonitrile and methylene chloride (v/v = 9:1) solution and also increased the intensity of color and fluorescence over time. And various metal ions including Ag+, K+, Li+, Na+, Ca2+, Cd2+, Co2+, Ni2+, Zn2+, Ba2+, Mg2+, Fe2+, Cs+, Al3+, Fe3+, Hg2+, Cu2+, Tb3+, Eu3+, Gd3+ caused less or smaller spectral changes. The 2:1 stoichiometry of sensor complex 1+ Al3+ was confirmed by Job’s plot based on fluorescence emission titration. Keywords: Rhodamine 6G, Aluminium, Fluorescent, chemosensor
