Whilst the pristine bent-core compounds do not show mesomorphism, the doped materials display smectic mesophases inside indium tin oxide cells assisted by the selective solvation of the lithium ions in the ethylene-oxide blocks. The dielectric response of the materials in the high-frequency range is controlled by the chemical composition of the bent-core structure, and the presence of lithium ions promotes direct current conductivity at low frequencies, in the σdc ∼ 10-5 S cm−1 range, which can be enhanced to σdc ∼ 10-4 S cm−1 via trans-to-cis photoisomerization of azobenzene groups. The dynamic and dual character of these materials (responding to low and high frequency electrical fields), the formation of ferroelectric crystals capable to store energy, and their interactions with light, will be applied to develop new energy devices. info:eu-repo/grantAgreement/ES/DGA/E47-23R info:eu-repo/grantAgreement/ES/MICINN-FEDER/PID2021-122882NB-I00 info:eu-repo/grantAgreement/ES/MINECO/BES-2016-078753 info:eu-repo/semantics/openAccess by http://creativecommons.org/licenses/by/3.0/es/ 5.3 2023 PHYSICS, ATOMIC, MOLECULAR & CHEMICAL 6 / 40 = 0.15 2023 Q1 T1 CHEMISTRY, PHYSICAL 58 / 178 = 0.326 2023 Q2 T1 0.918 2023 Atomic and Molecular Physics, and Optics 2023 Q1 Electronic, Optical and Magnetic Materials 2023 Q1 Spectroscopy 2023 Q1 Materials Chemistry 2023 Q1 Physical and Theoretical Chemistry 2023 Q1 Condensed Matter Physics 2023 Q1 10.3 2023 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Zaton, Daniel Castillo-Vallés, Martín (orcid)0000-0003-4333-6498 Baldini, Asia Pease, Jonathan Leader, Natalie Kamalul Aripin, Nurul Fadhilah Giacinti-Baschetti, Marco Ros, M.
