Abstract
Synthesis of several new podands, bearing various terminal chromophori c functions of formazan (9-11), verdazyl (18-20) and verdazylium salt (21-23) types and having a different length of oligooxyethylene bridge between chromophoric units, is developed. Calculated (Alchemy-2000) a nd found (EPR data) distances between spin centers in bis-radicals 18- 20 correlate well. Such spin-labeled species could be good models for the EPR study of host-guest interactions involving ethylene glycol-bas ed podands.
