New derivatives of diketopyrrolo[2,3-f]indole (DPIs) for organic electronics

This bachelor's thesis deals with semiconducting materials based on diketopyrroloindoles, their preparation and possible applications. In the theoretical part of the thesis, a current overview of the issues of organic electronics and photonics is presented, and technologies using the potential of organic molecules to behave as semiconductors capable of transmitting electrical energy are presented. A brief history highlights important milestones for organic conductive molecules and polymers, including important categories of high performance organic pigments and dyes such as diketopyrroloindoles (DPI). In other parts of the work, the synthetic approaches known so far in the preparation of DPI themselves are summarized, with a focus on their thiophene analogues and related derivatives. In the experimental part, the preparation of the basic molecule of the DPI skeleton is described. Finally, three derivatives differing in the character of the aliphatic side chain from a series of branched, linear and bulky substituents prepared by means of N,N'alkylation reactions are presented
