Chemical structure of 4,9-Dibromo-2,7-bis(2-octyldodecyl)benzo[lmn][3,8]phenanthroline-1,3,6,8(2H,7H)-tetraone, CAS No. 1100243-35-3.


With large branched side-chains, 4,9-Dibromo-2,7-bis(2-octyldodecyl)benzo[lmn][3,8]phenanthroline-1,3,6,8(2H,7H)-tetraone (also known as NDI2OD-Br2) adds solubility to the polymer semiconductors by functioning as repeating units in the back-bone. Also, polymers with NDI2OD-Br2 have the tendency to crystallise when they are built into films to boost device performance.
