Organic semiconductor materials are being developed and researched very actively, which opens up opportunities for the development of many modern fields of science and technology. Before the synthesis of new substances, it is extremely important to competently consider their structure, as it will depend not only on the conductive and electrochemical properties of future compounds, but also on their phase behavior, solubility, the ability to certain types of packing in the crystal, which affects the electrical characteristics and the possibility of creating devices based on them. The structures represented by the combination of electron-donor (D) and electron-acceptor (A) parts (D-A) are very interesting, since the variation of different strength and nature of D and A units makes it possible to control in a wide range of molecular energy levels, achieving the desired properties in the resulting compounds. Organic molecules consisting of condensed heteroaromatic links are of particular interest. The rigid structure of such compounds provides π-conjugation with good conductivity, high oxidation stability and dense molecular packing. Synthesis schemes of new oligomers and results of studies of electrochemical, optical and thermal properties, phase behavior of substances will be presented. Based on the obtained data, the interrelationships between the structure and properties of the obtained series of oligomers will be revealed and presented, namely, how the replacement of individual parts of the molecule affects the final properties. Prospects of application of the obtained materials in applications of organic and hybrid electronics will be evaluated.
