Using atomic force microscopy the aggregation of sulfonic tosylate pyrimidinophane on pyrolytic graphite surface was studied in the concentration range of 2.9 . 10 -3‑29 . 10 -3 M. It was shown the pyrimidinophane forms spherical aggregates on the solid hydrophobic surface. Size and shape of these aggregates are almost independent of a concentration of the compound. But when a concentration reaches value 29 mM the aggregates transform to a uniform film. This paper presents a systematic explanation of nature of investigated pyrimidinophane’s surface aggregation.
