Original Abstract

Organic electrochemical transistors (OECT) are used in a wide range of applications from energy-harvesting technologies to bioelectronic devices. The operation of these transistors is based on ion exchange between the environment and the organic semiconductor, and therefore on the mixed ionic-electronic conduction of conjugated polymers. Ion exchange thus plays a key role in the overall performance of the device and its sensitivity. This work deals with the possibility of studying ion exchange using two independent detection methods. The basis for the study of ion exchange is the electrical detection of positive ions (in the case of using a p-type organic semiconductor) using a modified OECT. The process of ion exchange is also monitored by a second independent method, namely the fluorescence of an ion-selective fluorescence probe. This combination of methods could contribute not only to a better understanding of ion exchange, but could also play a key role in material research in determining the volumetric capacitance of organic semiconductors. This knowledge could also help to elucidate the processes behind cell stimulation in stimulation platforms.
