General description

4-(2,3-Dihydro-1,3-dimethyl-1H-benzimidazol-2-yl)-N,N-dimethylbenzenamine is a semiconducting organic molecule with a π-conjugated polycyclic system. It is a strong electron donor molecule that can be used for n-type doping. It shows conductivity of ~2 × 10−3 S/cm as a dopant. It also acts as a reagent for the reductive transformation of organic compounds.

Application

Air stable n-type dopant for n-channel Organic Thin Film Transistors (OTFTs) and solar cells (OPVs).
It is mainly used as a semiconductor based polymer for the fabrication of electronic devices, which include organic thin film transistors (OTFTs), polymeric solar cells (PSCs) and organic light emitting diodes (OLEDs).
