Abstract

The characterization of metal-contg. supramol. polymers by gel permeation chromatog. (GPC) or matrix-assisted laser desorption ionization time-of-flight mass spectrometry (MALDI-TOF MS) is complicated because of the interaction of the charged materials with the GPC column material in the first case and fragmentation due to the applied laser energy in the latter case. Recent advances made for the characterization of supramol. polymers based on terpyridine metal complexes utilizing GPC and MALDI-TOF MS are reported. In particular for GPC anal., the choice of solvent and additive was crucial for a successful characterization. Furthermore, MALDI-TOF MS spectra of these compds. are not straightforward to interpret. Both aspects are discussed in detail with the result of a better understanding and improved anal. possibilities of the mentioned supramol. polymers. Ruthenium complex of terpyridine terminated polystyrene and poly(ethylene oxide) are examd. [on SciFinder (R)]
