Polythiophene (PT) is an important conducting polymer for its outstanding optoelectronic properties. Here, we delineate the self-assembly-driven optoelectronic properties of PT-peptide and PT-polymer conjugates, taking examples from recent literature reports. PT-peptide conjugates made by both covalent and noncovalent approaches are discussed. Poly(3-thiophene acetic acid) (P3TAA) covalently coupled with Gly-Gly-His tripeptide, C-protected and deprotected tripeptide H 2 N-F-F-V-OMe, etc. exhibits self-assembly-driven absorbance, fluorescence, photocurrent, and electronic properties. Noncovalent PT-peptide conjugates produced via ionic, H-bonding, and π-stacking interactions show tunable morphology and optoelectronic properties by varying the composition of a component. PT conjugated with Alzheimer's disease peptide (KLVFFAE, Aβ 16−22 ) shows enhanced photocatalytic water splitting, cationic PT(CPT-I)-perylene bisimide-appended dipeptide (PBI-DY), and anionic PTperylene diimide-appended cationic peptide (PBI-NH 3 + ) conjugates and exhibits self-assembly-driven enhanced photoswitching and organic mixed electronic and ionic conductivity (OMEIC) properties. In the PT-polymer conjugates, selfassembly-driven optoelectronic properties of covalently produced PT-random copolymers, PT-block copolymers, PT-graf t-random copolymers, and PT-graft-block copolymer conjugates are discussed. The HOMO−LUMO levels of hyperbranched polymers are optimized to obtain better power conversion efficiency (PCE) in the bulk heterojunction (BHJ) solar cell than in linear polymers, and P3TAA-ran-P3HT (43 mol % P3TAA) conjugated with MAPbI 3 perovskite exhibits higher PCE (10%) than that with only P3TAA hole-transporting material. In the ampholytic polythiophene (APT), on increasing pH, the morphology changes from the vesicle to fibrillar network for the dethreading of the PT chain, resulting in a red shift of the absorbance peak, an enormous increase in PL intensity, lowering of the charge transfer resistance, and an induction of Warburg impedance for the release of quencher I − ions. The PT-g-(PDMAEMA-co-PGLU-HEM) graft copolymer selfassembles with Con-A lectin, causing fluorescence quenching, and acts as a sensor for Con-A with a LOD of 57 mg/L. Varying sequences of the block copolymer containing pH-responsive PDMAEMA and temperature-responsive PDEGMEM grafted to the PT backbone shows different self-assembly, optical, electronic, and photocurrent properties depending on the proximity and preponderance of the block sequence on the PT backbone.

Recently, a great deal of research has been focused on developing interesting polymeric hybrid materials for different optoelectronic applications. For this purpose, we have synthesized dinonyl disulfonic acid-doped polyaniline-block-polythiophene (PANI-b-PT-DNNDSA, PABT) and dinonyl disulfonic acid-doped polyaniline-ranpolythiophene (PANI-ran-PT-DNNDSA, PART) by emulsion polymerization using an ammonium persulfate (APS) initiator and DNNDSA as the surfactant-cum-dopant. The polymers were characterized by size exclusion chromatography (SEC), 1 H NMR, and other spectroscopic techniques. SEC and X-ray photoelectron spectroscopy (XPS) analyses indicate that PABT has the composition PANI 34 -b-PT 16 -DNNDSA 11 . A polymerization mechanism is proposed for both PABT and PART systems. In the PABT-Ag system, the UV−vis, fluorescence, X-ray diffraction (XRD), and microscopic techniques suggest that Ag nanoclusters (AgNCs) are formed and stabilized by sulfur atoms of the PT chain via soft acid−base interactions. XRD data indicate a lamellar structure of PABT/PART systems, and SEM/TEM studies indicate a fibrillar network morphology. However, in PABT-Ag and in PART-Ag systems, sheet morphologies with tiny nanoparticles of raspberry architecture are noticed. Particle size measured from HRTEM images show nanocluster sizes (∼3.5 nm) comprised of about 10 Ag atoms for both PABT-Ag and PART-Ag systems. The absorption peaks of PART showed 5−8 nm blue shifts from PABT attributed to heteroatom nonbonding (pπ−dπ) interactions between closely spaced nitrogen and sulfur atoms of the PART conjugated chain, and fluorescence spectra also supports it. XPS spectra indicate ∼64%/∼61% doping of PANI by DNNDSA in PABT/PART systems. The dc conductivity and current−voltage (I−V) data indicate a semiconducting nature, and AgNCs cause an enhancement of conductivity. PART exhibits ∼3.5 times higher current than a PABT system, and on irradiation with white light, photocurrent increases 2.5−3 times in the AgNC coupled systems, also exhibiting electronic memory. The photocurrent growth in PART is faster than PABT, and in PABT-Ag and PART-Ag systems, growths are faster than those of pure PABT and PART systems, suggesting AgNCs play an important role in the enhanced photocurrent.
