Abstract Spatiotemporal control of ion conductivity is a key issue for creating emerging fields functional ion‐conducting nanomaterials. In the present paper, we demonstrate formation hetero‐smectic lamellar structures, which are formed by nanosegregation hydrophobic liquid crystalline (LC) azobenzene side chains and hydrophilic acrylic acid via polymer main in side‐chain LC (SCLC) copolymers, reversible photoswitching proton conductivity. Proton‐conducting SCLC copolymers with different contents synthesized free‐radical copolymerization. The nature polymers investigated polarized optical microscope observation, differential scanning calorimetry X‐ray scattering measurements. Ultraviolet (UV)–visible absorption spectroscopy grazing incidence measurements reveal copolymer thin films. Proton films evaluated impedance under temperatures relative humidity conditions sequential UV light irradiation. These results indicate that stable around one order magnitude attributed to trans – cis photoisomerization offer opportunity applications photo‐functional nanomaterials including biomimetic ionic signal transduction devices neuromorphic devices. © 2024 Society Chemical Industry.

Abstract Proton conduction is important in both fundamental research and technological development. Here we report designed synthesis of crystalline porous covalent organic frameworks as a new platform for high‐rate anhydrous proton conduction. By developing nanochannels with different topologies pathways loading neat phosphoric acid to construct robust carrier networks the pores, found that pore topology crucial Its effect on increasing conductivity an exponential mode other than linear fashion, endowing materials exceptional conductivities exceeding 10 −2 S cm −1 over broad range temperature low activation energy barrier down 0.24 eV. Remarkably, size controls mechanism, where mesopores promote via fast‐hopping while micropores follow sluggish vehicle process. Notably, decreasing content drastically reduces greatly increases barrier, emphasizing pivotal role well‐developed network transport. These findings insights unveil general transformative guidance designing framework systems ion conduction, storage, conversion.
