Synthesis of Hyperbranched Polypyridine via a Cross Coupling Approach as an n‐Type π‐Conjugated Polymer

Abstract: The synthesis of an n‐type π‐conjugated hyperbranched polymer, hyperbranched polypyridine, is described. The polymer is obtained by copolymerization of 2,4,6‐tribromopyridine and 2,5‐dibromopyridine via chain‐growth condensation polymerization catalyzed by Ni(dppp)Cl2. The NMR and fourier transform infrared results indicate the successful introduction of the branching unit into polypyridine by this cross coupling approach. The results of UV–vis spectroscopy and cyclic voltammetry suggest that the introduction … Show more

“…Although the predicted molecular weight based on the polymerization conditions (i.e., 1.5 mol% of Ni catalyst) was 6000, the mass spectrum of HBPPyBe indicated mass numbers in the range of 1000-4900, and all peak intervals corresponded approximately to the weight of the repeating unit, thereby suggesting the successful polymerization of HBPPyBe. It should be noted that the MS signals of the LPPy polymer appeared at a lower range, i.e., 1000-1500, likely due to poor solubility at the polymerization stage [41]. In general, the HBPPyBe polymers were insoluble in Fig.…”

“…2 shows the FT-IR spectra of HBPPyBe and the simulated spectrum for the branching unit. The simulated spectrum for the linear unit was reproduced from our previous study for comparison [41]. In the measured spectra, the absorbance at 1540 cm −1 increased with the BeBr 3 /PyBr 2 ratio.…”

“…We demonstrated several model catalytic reactions in this article, but other challenging catalytic reactions will be investigated by introducing various catalytically active sites. In addition, electro-catalytic processes using hyperbranched polymers could be our next area of interest, as the syntheses of several π-conjugated hyperbranched polymers have been recently demonstrated [51,52,53,54]. Further studies would be able to develop more attractive and exciting catalytic systems, which we believe will contribute to a sustainable future by green chemistry.…”
