Description General description Naphtho[1,2-b:5,6-b′]dithiophene (NDT) is a π-conjugated naphthodithiophene derivative that has symmetrical planar structures. It is mainly utilized in the development of semiconductors due to its high charge mobility and high current on/off ratios. Application NDT has donor-acceptor copolymers which can be used in the fabrication of organic electronic devices such as organic light emitting diodes (OLEDs), organic solar cells (OSCs) and organic field effect transistors (OFETs). This semiconducting material has been used in the synthesis of copolymers that show the highest mobility (>0.5 cm2 /Vs) in an NDT-based OFET device to date. Packaging 500 mg in glass insert
