Alteration of selectivity in rhodamine based probes for Fe(iii) and Hg(ii) ion induced dual mode signalling responses
The probes for metal ion induced chromo- and fluorogenic signalling responses alter their selectivity depending upon the nature of substituent as well as a function of solvent medium. 2 has shown selectivity towards Fe(iii) ion, 4 towards Hg(ii) ion while 3 is responsive towards both Fe(iii) and Hg(ii) ions.
