For the resultant polymers, the growth in the pyrene quantity results in the reduction of π-order. The decrease in π-order does not inevitably depreciate the organic field-effect transistor (OFET) mobility. A competitive mechanism between molecular fractionation and naphthalene diimide (NDI)-pyrene interactions is proposed. For moderate pyrene incorporation, molecular fractionation is dominant. Form I crystallites are fragmented, increasing the rigid amorphous fraction (RAF) regions. As for high pyrene content, the NDI-pyrene interactions take the lead, facilitating the establishment of a form II polymorph. The RAF can strengthen the interconnection among polymer crystallites. Overall, this work demonstrates a novel approach to intensifying the intrachain interconnection among polymers by the donor-acceptor (i.e., NDI-pyrene) complementary interactions, offering pathways for efficient charge transporting in OFETs. ? |
