The recently developed combination of vacuum electrospray deposition (ESD) and scanning tunnelling microscopy (STM) is here compared to commonly-used analytical techniques GPC and NMR. We study three DPP-based polymers, of which only two produce clearly-resolved NMR spectra. Our subnanometre-resolved images provide, in one single experiment, detailed information about complete mass distributions and exact polymer sequences, including the identification of polymerisation defects. We, therefore, show that ESD-STM represents a new powerful analytical tool, successfully benchmarked against NMR and GPC when these methods are viable, and that can be used to characterise with equal accuracy polymers that are inaccessible by traditional techniques.
