Poly[[1,2,3,6,7,8-hexahydro-2,7-bis(2-octyldodecyl)-1,3,6,8-dioxobenzo[lMn][3,8]phenanthroline-4,9-diyl][2,2'-bithiophene]-5,5'-diyl]

Classification

Organic n-type semiconducting materials, Organic photovoltaics, Polymer solar cells, Electron-acceptor polymers, OFETs, Perovskite solar cells.

Applications

PNDI(2OD)2T, a copolymer of naphthalene diimide (NDI) and bithiophene unit, has been intensively studied for use as an electron acceptor in polymer solar cells. This is due to its high electron mobility, high electron affinity, and broad light absorption. All polymer solar cells with PNDI(2OD)2T as an acceptor and J51 as a donor (fullerene-free) have demonstrated a power conversion efficiency over 8%.
PNDI(2OD)2T is also known as a high-mobility n-type polymer semiconductor. PNDI(2OD)2T-based OFET devices have electron mobilities up to 0.45–0.85 cm2V-1 s-1.
