“…possibly several hydrogen bond interactions (Scheme 1), 32 directly affect electrochemical properties of the resulting polymers since such an interaction changes the structure of polymer molecule. 33,34 In the present work, novel PICA nanowires have been prepared by a facile, one-step and template-free electrodeposition method. The structural characterization, morphology and thermal stability of the as-formed PICA lms were investigated.…”

“…Yamamoto and co-workers were the early developers of some of these conjugated systems, exploring poly(benzimidazole-4,7-diyl)s with various solubilizing side groups − and later venturing into copolymers incorporating aryleneethynylene and thiophene units. ,− Some of these early publications hint at the potential of doping but do not probe the fundamental transitions that occur upon treatment of poly(benzimidazole-4,7-diyl)s with strong acids or bases. More recently, Toppare and co-workers have investigated H-bonding interactions between BI and ethylenedioxythiophene (EDOT). − …”

We present the synthesis and characterization of poly (2-alkyl-benzimidazole-alt-9,9-dihexylfluorene). An improved microwave-assisted synthesis of the monomers 4,7-dibromo-2-heptyl-1H-benzo [d]imidazole and 4,7-dibromo-2-(heptan-3-yl)-1H-benzo[d]imidazole was developed. The monomers were polymerized with 9,9-dihexylfluorene-2,7-diboronic acid bis(1,3-propanediol) ester using Suzuki crosscoupling to yield the corresponding poly(2-alkyl-benzimidazole-alt-9,9-dihexylfluorene)s. The polymers were characterized by both traditional optical and thermal properties in conjunction with experiments yielding strong evidence to suggest controllable chemical doping of benzimidazole moieties. Based on ultraviolet−visible spectroscopy (UV−vis) and cyclic voltammetry (CV) data, the band structure of these benzimidazole-containing polymers may be manipulated through treatment with acids or bases to achieve polycationic or polyanionic products. Protonic doping is shown to significantly impact the electronic properties of the parent polymer; the optical band gaps were shown to shift +0.07 and −0.33 eV for the acid-and base-doped polymers, respectively. Herein, we quantify the changes in band structure between the neutral and charged polymers.
