Summary: Two donor-acceptor (D-A) type conjugated porous polymers (CPPs), P(TPA-TBTh) and P(TPA-F-TBTh), were synthesized on ITO glass electrodes through Stille coupling reaction under solvothermal conditions. The CPPs exhibited ambipolar properties in electrochromic switching and showed different morphologies. The introduction of fluorine atoms onto the polymer skeleton reduced the energy levels and band gap, resulting in a lower band gap for P(TPA-F-TBTh). Additionally, the non-fluorinated and di-fluorinated CPPs exhibited different electrochromic kinetic properties. These D-A type CPPs provide new designs for multicolor electrochromic materials with ambipolar properties and rare green reduction states.

Summary: Two conducting macromolecules, P1 and P2, with adjustable color changes under an electric field were successfully fabricated on the ITO substrate via electrochemical polymerization for the first time. The P1 film exhibited yellowish-brown color in neutral and reduced states, and dark brown color in oxidized states, while the P2 film showed orange color in neutral states, brownish orange color in oxidized states, and dark brown color in reduced states. P1 showed higher conductivity, shorter switching time, and better stability, while P2 exhibited advanced chromic and electron-withdrawing characteristics attributed to the substituted phenyldiazenyl units and lower oxidation potential.

Summary: Conjugated polymers often have both crystallized and amorphous regions in the solid state, making it challenging to accurately determine their precise microstructures. This study obtained crystals of two typical conjugated polymers through a controlled self-assembly process, allowing for the determination of crystal structures using X-ray techniques and molecular simulations. The highly oriented polymer chains in the crystals exhibit higher mobilities and lower hopping energy barriers compared to spin-coated thin films.

Summary: The energy levels between PTB7-Th/ITIC and ZnO in a photovoltaic device are well aligned, and a double dipole is formed between PTB7-Th/ZnO. ZnO is commonly used as a cathode interface layer due to its ability to extract electrons from the active layer. This study focuses on the electronic structure of the interface between ZnO and an active layer containing PTB7-Th and ITIC. Various electron spectroscopy techniques were used to determine the energy levels of these materials at their interface. The findings show that PTB7-Th and ITIC are well aligned with ZnO, and two dipoles are formed at the PTB7-Th/ZnO interface.

Summary: Polyacrylic acid complexed with polyaniline (PAA/PANI) composite materials have the potential to form organic mixed ion-electron conductive (OMIEC) films, which can be used in optoelectronic and energy storage applications. The composite films are formed through an acid-base reaction, resulting in strong electrostatic interactions and intermolecular hydrogen bonds between PANI and PAA. The separation of PANI-rich domains from PAA-rich matrix in the composite films is observed. The electrical conductivity of the composite films is higher when the content of PANI is 33 wt%, due to the high ionic-electronic coupling at the interface between phase-separated regions.
