    Carbon-carbon (CC) backbone polymers are a class of polymer materials widely used in daily life.



    The research group of Prof.

    The research team first optimized the polymerization conditions and tried a series of catalytic systems composed of different Ni compounds (R'–Ni–X) and different ligands (L1–L6) to induce benzyl diazoacetate (1a) The polymerization reaction was studied, as shown in Figure 2

    Next, the research team studied the polymerization kinetics of BT–Ni(dppp)Cl-initiated polymerization of diazo monomer 1a (internal standard is polystyrene; Mn = 41.

    3.


    Since BT-Ni(dppp)Cl showed excellent performance during the polymerization of diazotate, the team tried to study the functional polymer with similar Ni(II)-complex ends to initiate the living polymerization of diazoacetic acid, thereby obtaining Functional block copolymers


    Figure 5.


    Using the above-mentioned functional polymer P3HT-initiated diazotate polymerization strategy, a series of π-conjugated copolymers with controllable molecular weight and structure, such as amphiphilic block copolymers, can be prepared


    The significance of this study is to establish a method for the controllable polymerization of diazotes with non-noble metal Ni(II) catalysts, and to easily synthesize CC backbone polymers and π-conjugated interpolymers with substituents on each backbone carbon atom.
