Fluoroionophores with Phenanthridinyl Units

Novel fluoroionophores bearing two (1) and one (2) fluorophoric6-phenanthridinyl units attached by a short methylene spacer onto nitrogen atoms of 7, 16-diaza- and aza-l8-crown-6 rings have been prepared in high yields. The fluoroionophores exhibited the ability to signal binding of certain metal cations through the specific complexation induced shifts (CIS) of phenanthridine protons in H-1 NMR spectra as well as by the large intensity enhancements in fluorescence spectra. The X-ray structure analysis of [1, K+(C2H4Cl2)] picrate complex revealed that K+ is nine-coordinated, using all donors from the diazacrown ring, one chlorine atom from 1, 2-dichloroethane solvent molecule and both nitrogen donors from syn-oriented phenanthridine units.
