Original Abstract

Nowadays, there are several organic semiconductors with relatively high charge carrier mobilities which are used for the construction of organic field-effect transistors (OFETs). In particular, small molecules such as derivatives of pentacenes, rubrenes and perylenes, and polymers such as P3HT and PCDTBT have been widely studied so far. At the present time, known dyes and pigments are modified for use in organic electronics. To this group of organic semiconducting materials also include diketopyrrolopyrroles (DPP) that represent the family of originally high performance pigments with high thermal and light stability and weather fastness. The aim of this study is to elucidate the influence of diketopyrrolopyrroles derivatives chemical structure modifications on the performance of organic field effect transistors (OFETs). Performance of OFETs is strongly dependent on the charge carrier injection from contact and their transport within the first organic semiconductor (OSC) monolayers at the interface with the gate dielectric. Therefore, in this contribution we focused on modification of self-assembled monolayers (SAMs) on OFETs prototypes prepared on silicon substrates (Fraunhofer IPMS). Other optimization of OFETs was performed in following parameters: choice of solvent, spin-coating and thermal annealing optimization. Results of this study charge carrier mobility, contact resistance, on/off ratio will be discussed within this contribution. The studied materials showed to be promising for organic electronics applications based on the obtained results.
