ndi-2hd-2br, 1459168-68-3
Chemical structure of 4,9-Dibromo-2,7-bis(2-hexyldecyl)benzo[lmn][3,8]phenanthroline-1,3,6,8(2H,7H)-tetraone, CAS No. 1459168-68-3.



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)TPNDI(2HD)2T and PNDI(2HD)S, are p-type high-mobility polymers used for high-performance OFETs and all-PSCs.
