Original Abstract

In this paper, the possibility to use diketopyrrolopyrrole (DPP) for the construction of electrical devices designed to interact with animal cells was studied. For this purpose, the biocompatibility and electrical properties of the selected DPP derivative (3,6-bis(5-(benzofuran-2-yl)thiophen-2-yl)-2,5-bis(2-ethyl-hexyl)pyrrolo[3,4-c]pyrrole-1,4-dione) [referred as DPP(TBFu)2] were researched. The electrical properties were studied using model organic feld-efect transistors. Mainly investigated was under what conditions maximum charge carrier mobility can be achieved. Using the cumulative efect of self-assembled monolayers on dielectrics and electrodes and detailed thermal analysis of the DPP, a higher charge carrier mobility was achieved than has been previously reported (5.5×10−3 cm2 V−1 s−1). The biocompatibility was studied based on a culture of 3T3 fbroblasts. This research revealed that DPP(TBFu)2 can be used in applications involving direct contact with living animal cells. The conclusions found with these model devices can be applied to components suitable for biosensing applications, e.g., water- or electrolyte-gated organic feld-efect transistors.
