“…We anticipate that it is possible to control the domain size in the composite film consisting of block copolymer and n-type small molecule (PCMB), via self-assembly of the block copolymer, and it also assists the regular alignment of each domain. Previously we reported that the p-type diblock copolymer, Poly(3-hexylthiophene)-b-poly(ethylene oxide) (P3HT-b-PEO) was synthesized by coupling between regioregular P3HT and PEO homopolymers, and that the regular morphology with small size can be obtained in the thin films of P3HT-b-PEO blended with PCBM [17]. A similar strategy using P3HT-b-poly(4-vinylpyridine) was reported independently [18].…”

Poly(3-hexylthiophene)-block-polystyrene (P3HT-b-PS) was synthesized by Suzuki coupling reaction between P3HT and PS, prepared by Grignard metathesis polymerization and atom transfer radical polymerization (ATRP), respectively. The formation of block copolymer was confirmed by gel permeation chromatography (GPC) and NMR. Differential scanning calorimetry (DSC) thermogram of block copolymers showed glass transition of PS block and melting/crystallization of P3HT block, suggesting a microphase separated structure, which was also confirmed by atomic force microscopy (AFM) images and UV-vis absorption spectra. The annealing effect on the morphology of the composite films consisting of 6]-phenyl-C 61 -butyric acid methyl ester (PCBM) was investigated. Photovoltaic cells fabricated using P3HT-b-PS and PCBM were evaluated.

“… 126 Block copolymers, macromolecules with distinguished segments of ionic and electronic conduction, represent another example of the heterogeneous type. 127 While heterogeneous OMIECs are subject to the microphase separation between ion conducting and π-conjugated components, the materials of the homogeneous type do not suffer from this issue. Homogeneous OMIECs generally incorporate charged or polar groups, often through side chain engineering utilizing EG-based moieties, within a single material, producing a bulk mixed conduction phase by distributing ion solvating fragments along the polymer backbone.…”

Expanding the toolbox of the biology and electronics mutual conjunction is a primary aim of bioelectronics. The organic electrochemical transistor (OECT) has undeniably become a predominant device for mixed conduction materials, offering impressive transconduction properties alongside a relatively simple device architecture. In this review, we focus on the discussion of recent material developments in the area of mixed conductors for bioelectronic applications by means of thorough structure–property investigation and analysis of current challenges. Fundamental operation principles of the OECT are revisited, and characterization methods are highlighted. Current bioelectronic applications of organic mixed ionic–electronic conductors (OMIECs) are underlined. Challenges in the performance and operational stability of OECT channel materials as well as potential strategies for mitigating them, are discussed. This is further expanded to sketch a synopsis of the history of mixed conduction materials for both p- and n-type channel operation, detailing the synthetic challenges and milestones which have been overcome to frequently produce higher performing OECT devices. The cumulative work of multiple research groups is summarized, and synthetic design strategies are extracted to present a series of design principles that can be utilized to drive figure-of-merit performance values even further for future OMIEC materials.

Abstract:The diblock copolymer PTPA-b-PS consisting of poly(4-butyltripheneylamine) (PTPA) and polystyrene was prepared by atom transfer radical polymerization followed by C-N coupling polymerization. Three types of block copolymers with different contents of polystyrene segment were prepared. The formation of block copolymer was confirmed by 1 H NMR spectra and gel permeation chromatography (GPC) profiles. Time of flight (TOF) measurement revealed that the block copolymer showed higher hole mobility up to 1.3 × 10 −4 cm 2 /Vs compared with PTPA homopolymer. The surface morphology of block copolymer films blended with [6,6]-phenyl-C 61 -butyric acid methyl ester (PCBM) was investigated by Atomic force microscopy (AFM). Introduction of polystyrene segment provided microphase-separated structures with domain sizes of around 20 nm. The photovoltaic device based on PTPA-b-PS, PTPA, and PCBM exhibited higher efficiency than that of homopolymer blend system.
