Original Abstract

Organic semiconductors are suitable for application in biosensors and sensors based on transistors. The influence of position solubilization group on diketopyrrolopyrrole core bonded throught oxygen (O) or nitrogen (N) on the performance of diketopyrrolopyrrole-based organic field-effect transistors (OFETs) is studied. The lowest mobility 1·10-9 cm2/Vs was observed for nonsymmetric substitution O,N of “EthylAdamantyl” solubilization group. Measurable charge carrier mobility was observed due to reduction of the density of charge trapping states after application of organosilane self-assembled monolayers (SAMs) on thinner gate-dielectrics (90 nm). We report similar drift mobility 1·10-7 cm2/Vs for smallest solubilization group “butyl” as for the biggest group “EthylAdamantyl” in N,N and O,O substitution prepared by spin-coating.
