In this work, the preparation of head‐to‐tail regioregular poly(6‐(1‐tridecenyl)‐pyridine‐2,5‐diyl) (PPy) and its post‐functionalization via hydroboration is described.PPyhas been prepared via Kumada‐coupling polycondensation with different catalytic systems. Number‐average molecular weights of up toMn= 14.7 kDa (PDI = 2.0, DPn= 60) can be obtained, as determined by gel permeation chromatography relative to polystyrene standards.PPyhas been characterized by MALDI‐TOF MS, optical spectroscopy, and cyclic voltammetry. The regioregularity of the material is confirmed by comparison with a head‐to‐head‐tail‐to‐tail regioregular polybipyridine (PBPy,Mn= 14.0 kDa, PDI = 1.5, DPn= 29). The 1‐alkenyl‐substituents inPPyhave been introduced to provide functional groups for post‐functionalization. Herein, it is also demonstrated that these internal double‐bonds are sufficiently reactive to allow for hydroboration with 9H‐borabicyclo[3.3.1]nonane (9H‐BBN), to furnish an intermediate borylated polymer (PPyHB). Treatment ofPPyHBwith strong acids, and characterization of the deborylated polymerPPyH2proves quantitative conversion of the precursor polymer.
