The getting knowledge of the methods of chemical compounds synthesis on the planned construction site, both in terms of arrangement of atoms and functional groups, as well as spatial structure, allowed to obtain a number of new molecular receptor systems that are capable to creating host-guest complexes. The paper will present the way of the proceedings from molecular receptor to new material with this receptor, so in other words from individual molecules to the new material with specific and previously planned properties. This process is presented for two types of molecules: aryloboronic acids and terpyridine. The ability for rapid and reversible formation of boronic acids, esters of 1,2- and 1,3-diols resulted in that these compounds were used for the synthesis of sugar receptors and consequently to build the new generation of the sensors of sugars. 2,2’:6,2’-Terpyridine is ligand, that in solution forms complexes with most transition metal ions. This compound is used for the synthesis of functional polymers, dendrymers and fluorescent sensors of ions. The presentation of the applicability of molecular receptors in the preparation of new functional materials promotes the new approach to the work of chemists. The basic research in which we define the properties of individual molecules and molecular receptors can be the beginning of the application of these compounds in the material chemistry. Additionally it can lead to the synthesis of the new materials with the specific properties or the selective construction of the measuring systems. The process from the molecule that is characterized by well-studied properties to modern material chemistry is limited only by the imagination of chemists and by the demand for new organic materials in the industry and by the new generation of the selective measurement systems.
