Аннотация:Abstract—A new carbazolecontaining naphthodithiophene heteroaromatic compound, 5,6bis[9(2
decyltetradecyl)9Hcarbazol3yl]naphtho[2,1b:3,4b']dithiophene (M1), was synthesized to be subse
quently used as the weak donor structure for the construction of narrow bandgap D–A conjugated polymers
in terms of the “weak donor–strong acceptor” concept. The composition and structure of M1 were con
firmed by the data of elemental analysis and IR and 1H and 13C NMR spectroscopy. The optical and electro
chemical characteristics of the product were measured. The compound M1 was shown to have lowlying
HOMO (–5.57 eV), which is favorable for high opencircuit voltage and to be suitable as a promising weak
donor moiety in the D–A conjugated polymer for photovoltaic applications.
