    • It could be argued that the exchange with peaks located at ∼1.5 ppm (methylene of alkyl chain) also involves the thiol signal at ∼1.4 ppm, but: (1) the contribution of thiols is minor compared to methylene (ratio ≈ 1: 45), (2) the situation is similar for ethoxy and isopropoxy groups, and (3) the differences in the diffusion curves are also observed with the methyl groups of the alkyl chain (signal at ∼1 ppm)

    • In turn, this might explain why we found in preliminary experiments bigger cell parameters when the siloxane surface is functionalised by methyl groups rather than mercaptopropyl groups, other synthesis conditions being equal
