Abstract

The electron-transfer matrices for matrix-assisted desorption/ionization (MALDI)-mass spectrometry of small non-polar, redox-active analytes are evaluated. Results show that terthiophene can be used successfully as a matrix for the mass spectral characterization of the electronically conducting polymer poly(3-hexylthiophene). The molecular weight values obtained by MALDI-MS are significantly lower than those provided by gel permeation chromatography. In the analysis of redox-active dendrimer, anthracene and terthiophene are the gentlest MALDI matrices, causing much less fragmentation than dithranol or 2,5-dihydroxybenzoic acid.
