General description

PBTTT-C14 is a semiconducting material which is used as a hole transporting material (HTM). It has an ordered structure and crystal orientation which result in a high performance conducting material.

Application

PBTTT-C14 based conjugated polymers can potentially be used in combination with fullerenes and P3HT for the fabrication of a wide range of devices like organic field effect transistors (OFETs), organic photovoltaics (OPVs), solar cells (SCs) and photodiodes.
