The precisely defined cyclic catechol material (CyCat) was prepared from ortho-dimethoxybenzene in a phenolic resin-like synthesis and subsequent deprotection, featuring molecules with up to 32 catechol units. The CyCat’s chemical structure was carefully assessed via matrix-assisted laser desorption ionization time-of-flight mass spectrometry, proton nuclear magnetic resonance, diffusion ordered spectroscopy and high resolution electrospray ionization mass spectrometry experiments. The formation of colloidal aggregates of the CyCat material in alkaline solution was followed by dynamic light scattering and further verified by dropcasting CyCat from solution on highly oriented pyrolytic graphite, which was examined by Kelvin probe force microscopy.
