Solid-state 1 H NMR methods employing very-fast magic-angle spinning (MAS) are applied to hexa-alkyl-substituted hexa-peri-hexabenzocoronenes (HBC) as well as an alkoxy-triphenylene derivative. Firstly for the HBC derivatives, the effect of changing the alkyl substituent from i-propyl to t-butyl on the structure adopted in the solid phase is investigated. From single-quantum MAS spectra, differences...
