1-(4-Nitrophenyl)-benzimidazolium-based ratiometric chromogenic probes for cyanide ion
摘要:
1,3- and 1,4-bis-[1-(4-nitrophenyl)-benzimidazolium-3-methylene]benzene-based molecular probes interact selectively with cyanide ion to switch the absorbance from 270 nm to 376 nm and elaborate ratiometric chromogenic probes for the estimation of 1-270 mu M cyanide ion-the desirable concentration range for practical applications.
