With large branched side-chains, 4,9-Dibromo-2,7-bis(2-hexyldecyl)benzo[lmn][3,8]phenanthroline-1,3,6,8(2H,7H)-tetraone (also known as NDI-2HD-2Br) adds solubility to polymer semiconductors by functioning as repeating units in the back-bone.
Polymers prepared from this monomer, such as PNDI(2HD)T, PNDI(2HD)2T and PNDI(2HD)S, are p-type high-mobility polymers used for high-performance OFETs and all-PSCs.
