Owing to their potential of low-cost, low-temperature, environmentally-friendly manufacturability on stretchable and flexible substrates, organic semiconductor technology has already entered into our everyday life. Organic Field-Effect Transistors (OFETs) in particular are of interest for application in radio frequency identification tags, wearable electronics, sensors and OLED TVs and mobile devices, just to name a few. In order to make organic electronics an everyday reality, solution-processable high-mobility Donor-Acceptor type conjugated polymers such as P(NDI2OD-T2), BFS4 and PCDTPT, play a pivotal role. This thesis investigates the structure-function properties of such D-A co-polymers through a combination of OFET measurements and microstructural characterisation, the latter has carried out with synchrotron- and neutron-based techniques.
