Ion Mobility Mass Spectrometry to Probe Sequences in Supramolecular Copolymers
The analysis of the microstructure of supramolecular copolymers is difficult because of their dynamic character. Here, benzene-1,3,5-tricarboxamide (BTA) co-assemblies are analysed by ion mobility - mass spectrometry (IM-MS) to reveal the presence of various sequences. For example, the IM-MS mobilogram for hexamers composed of 4 units from a first monomer and 2 units from a second monomer is a broad distribution due to the presence of 9 possible isomeric sequences, which can be sorted out based on calculated collision cross-sections. This approach gives unprecedented information on supramolecular copolymer sequences.
