초록
A new assembly derived from 2,3-dibromo-5,6,7,8-tetrafluoroquinizarin and sodium diethyl-carbamodithiolate, was prepared as an efficient Fe3+ colorimetric chemosensor with high selectivity over other cations Fe3+, Na+, Mg2+, Pb2+, Cd2+, Ni2+, Ca2+, Cu2+, Hg2+, Zn2+ : from the dark blue to brown color change that is visible by eyes. This assembly produced large bathochromic shift of 228 nm in the presence of Fe3+ compared with the corresponding absorption maximum of the parent dye.
