| 罗丹明B乙二胺 | rhodamine B ethylenediamine | 950846-89-6 | C30H36N4O2 | 484.641 |
A new rhodamine-based chemosensor 2, which shows a reversible dual fluorogenic and chromo-response to Fe3+ in MeOH-HEPES buffer (10 mM, pH 7.4) (3:1 v/v), has been developed. The free solution of 2 is colourless and nonfluo-rescent which changes to pink with a strong fluorescence in the presence of Fe3+. Other metal ions (Hg2+, Ag+, Pb2+, Sr2+, Ba2+, Cd2+, Ni2+, Co2+, Fe2+, Mn2+, Cu2+, Zn2+, Ce3+, Cr3+, Mg2+, K+ and Na+) had no significant effect.
