“…In order to achieve the precise synthesis of optoelectric polymers, the first task is overcoming reaction kinetics and statistics. As shown in Figure , we have developed solid-phase electrosynthesis. − ,, In particular, electrosynthesis accelerates the reaction kinetics at the solid–liquid interface. The similar width of self-assembled molecules and iterative monomers is favored for dynamically allowing the top-down addition during iterative reactions.…”

The ionization degree, charge density, and conformation of weak polyelectrolytes can be adjusted through adjusting the pH and ionic strength stimuli. Such polymers thus offer a range of reversible interactions, including electrostatic complexation, H-bonding, and hydrophobic interactions, which position weak polyelectrolytes as key nano-units for the design of dynamic systems with precise structures, compositions, and responses to stimuli. The purpose of this review article is to discuss recent examples of nanoarchitectonic systems and applications that use weak polyelectrolytes as smart components. Surface platforms (electrodeposited films, brushes), multilayers (coatings and capsules), processed polyelectrolyte complexes (gels and membranes), and pharmaceutical vectors from both synthetic or natural-type weak polyelectrolytes are discussed. Finally, the increasing significance of block copolymers with weak polyion blocks is discussed with respect to the design of nanovectors by micellization and film/membrane nanopatterning via phase separation.

Electropolymerization is an important technique for surface functionalization, owing to its convenient and controlled synthetic pathways. The in situ synthesis of metallosupramolecular polymers (MSPs) utilizing coordination-driven metal ions and coordinating ligands as well as studying their potential applications using electropolymerization have been less explored. Herein, we demonstrated the formation of MSPs on a preterpyridinefunctionalized indium tin oxide (ITO) glass substrate by using Fe(III) ions and 4′,4⁗-(1,4-phenylene)-bis(2,2′:6′,2″-terpyridine) ligand. By providing an anodic potential, polymer growth occurred due to the strong coordination between the reduced metal ions (Fe(II)) and the bis-terpyridine ligand. The formation of the polymer was evident from the growth of the corresponding peaks in the cyclic voltammogram and UV−vis spectral profile. The surface morphology was characterized by using atomic force microscopy (AFM). The electrochromic (EC) properties of the electropolymerized MSP (EP-MSP) were studied by utilizing the metal-to-ligand charge-transfer color band of the redox-active Fe(II)-(terpyridine) 2 unit present in the MSP backbone. It was observed that the film exhibited an optical switching coloring time of 2.1 and 5.7 s for bleaching, a transmittance change of 54%, and a coloration efficiency of 142.6 cm 2 C −1 .
