- Abstract
A new carbazole-containing naphthodithiophene derivative—heteroaromatic compound 5,6- bis[9-(2-decyltetradecyl)-9H-carbazol-3-yl]naphtho[2,1-b:3,4-b']dithiophene (M1)—has been synthesized. The compound will be used by us as a weak donor structural block for fabricating narrow-bandgap D-A conjugated polymers. The composition and structure of M1 have been confirmed by elemental analysis data, IR spectroscopy, and 1H and 13C NMR. The synthesized compound has a low HOMO energy (-5.4 eV), which is favorable for a high open-circuit voltage. Monomer M1 can be used as a promising weak donor moiety in D-A conjugated polymers for solar photovoltaics.
