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: The anion and pH-sensing behaviors of a Ru(II)-bipyridine complex with dissociable protons in its secondary coordination sphere are used to create multiple Boolean and fuzzy logic systems. Changes in anions and pH significantly modulate the absorption, emission, and electrochemical behaviors of the metalloreceptor. The protonation-deprotonation behaviors of the metalloreceptor can be reversed and repeated multiple times, allowing it to demonstrate advanced Boolean functions.

Summary: Three donor-acceptor (D-A) type electrochromic copolymers with double-doping feature and narrow optical band gaps were synthesized. The solid films of these polymers exhibited different blue colors in the neutral states and switched to light blue-gray or gray after oxidation or reduction. These polymers showed favorable kinetic properties, especially in the near-infrared (NIR) region. The use of dithieno [3,2-b:2 ',3 '-d]pyrrole (DTP) units as building blocks for electrochromic copolymers to obtain D-A type ambipolar electrochromic polymers with dual fading processes is rare.

Summary: A grid-type complex containing dihydrazone ligand with thiophene rings was prepared by oxidative electropolymerization onto ITO electrode to form a purple thin film. The morphology of the polymer film was analyzed by SEM and AFM imaging, showing that the film obtained by electropolymerization method is homogeneous and uniform. The thin film exhibits color transition from purple to blue due to the stepwise reduction of poly-[Co-4(II)(L1-2H)(4)] into poly-[(Co2Co2I)-Co-II(L1-2H)(4)](2-) and poly-[Co-4(I)(L1-2H)(4)](4-). Its electrochromic properties such as long-term stability, coloration efficiency, and switching times have been investigated.
