Controlled self-assembly of molecular building blocks on solid substrates is a versatile method to create low-dimensional structures with preprogrammed morphology and functions. In this contribution, using theoretical tools, we demonstrate how the structure of large self-assembled molecular systems can be predicted based on individual properties of building blocks at play. In particular we focus on the role of directionality of interactions provided by discrete active centers being part of model star-shaped tectons. Our theoretical predictions are compared with available experimental data and hints on synthesis of organic functional molecules able to form various superstructures are given. The findings from the Monte Carlo modeling can be useful in designing of 2D supramolecular architectures as well as of covalently bonded structures resulting from on-surface polymerization reactions.
