Well-defined mono- and bifunctional, phenanthrolineterminated poly(ethylene glycol) and polyisobutylene capable of polymer network formation were synthesized. The starting materials mono- and bi-phenanthroline- (phen) terminated polyethylene glycols) (mPEG-phen, phen-PEG-phen) and polyisobutylenes (PIB-phen, phen-PIB-phen) were prepared by the Williamson synthesis and characterized by means of 1H NMR and MALDI-TOF mass spectrometry. According to UV-Vis spectrophotometry and ESI-TOF mass spectrometry, the phenanthroline-terminated polymers underwent quantitative complex formation with ferrous ions in solution. The aqueous solution of mPEG-phen shows selfassembly behavior. Important parameters, such as critical micelle concentration and hydrodynamic radius of the aggregates were also determined.
