dc.description.abstract | Two poly(naphthalene diimide)s (PNDIs) have been developed using p-phenylene ethynylene-based comonomers with either thiophene side chains (P(NDI-BT)) or bithiophene side chains (P(NDI-BBT)), and the effects of the length of conjugated side chains on electrochemical, optical, and morphological properties were investigated. Both polymers showed additional vibronic peaks due to the interchain π-π* transition, and a high absorption coefficient (α) of the order of 105 cm−1 was observed. P(NDI-BBT) gave higher α with narrower optical energy band gaps and lower lying the lowest unoccupied molecular orbital (LUMO) energy levels compared to those in P(NDI-BT). Interestingly, lower crystallinity was observed in P(NDI-BBT) than P(NDI-BT), which is the opposite of trends shown for reported polymers with conjugated side chains. Their charge carrier mobilities and photovoltaic properties were also investigated, and provide insight of designing NDI based n-type polymer semiconductors with conjugated side chians. © 2021 Elsevier Ltd | - |
