Organic semiconductors are actively developed and investigated, giving prospects for the development of many modern areas of science and technology. It is extremely important to think about the structure before synthesizing new materials, because it will determine not only the conductive and electrochemical properties of future compounds, but also their solubility and ability to certain types of packing in the crystal, which affects the mobility of charges and is important in the creation of devices. Compounds whose structure is represented by a combination of electron-donor (D) and electron-acceptor (A) parts (D-A structure) are very interesting, since the variation of different donor and acceptor units in the structure and their spatial arrangement makes it possible to control in a wide range of molecular energy levels, achieving the desired properties. Organic molecules consisting of condensed heteroaromatic links are of particular interest. Since the rigid structure of such compounds provides a π-conjugation with good conductivity, high oxidation stability and dense molecular packing. This work will present a series of semiconducting oligomers of D-A structure, which have donor heteroaromatic cores and acceptor functional groups connected by π-spacers. The following will be presented: synthesis schemes; results of studies of electrochemical, optical and thermal properties, phase behavior of substances. The interrelations between the structure and properties of these compounds, as well as how the change of links is reflected in the final properties will be revealed and shown. It is planned to evaluate the prospects of application of the obtained substances in various fields of organic electronics.
