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. 000131700 536__ $$9info:eu-repo/grantAgreement/ES/DGA/E47-23R$$9info:eu-repo/grantAgreement/ES/MICINN-FEDER/PID2021-122882NB-I00$$9info:eu-repo/grantAgreement/ES/MINECO/BES-2016-078753 000131700 540__ $$9info:eu-repo/semantics/openAccess$$aby$$uhttp://creativecommons.org/licenses/by/3.0/es/ 000131700 590__ $$a5.3$$b2023 000131700 592__ $$a0.918$$b2023 000131700 591__ $$aPHYSICS, ATOMIC, MOLECULAR & CHEMICAL$$b6 / 40 = 0.15$$c2023$$dQ1$$eT1 000131700 591__ $$aCHEMISTRY, PHYSICAL$$b58 / 178 = 0.326$$c2023$$dQ2$$eT1 000131700 593__ $$aAtomic and Molecular Physics, and Optics$$c2023$$dQ1 000131700 593__ $$aElectronic, Optical and Magnetic Materials$$c2023$$dQ1 000131700 593__ $$aSpectroscopy$$c2023$$dQ1 000131700 593__ $$aMaterials Chemistry$$c2023$$dQ1 000131700 593__ $$aPhysical and Theoretical Chemistry$$c2023$$dQ1 000131700 593__ $$aCondensed Matter Physics$$c2023$$dQ1 000131700 594__ $$a10.3$$b2023 000131700 655_4 $$ainfo:eu-repo/semantics/article$$vinfo:eu-repo/semantics/publishedVersion 000131700 700__ $$aZaton, Daniel 000131700 700__ $$0(orcid)0000-0003-4333-6498$$aCastillo-Vallés, Martín 000131700 700__ $$aBaldini, Asia 000131700 700__ $$aPease, Jonathan 000131700 700__ $$aLeader, Natalie 000131700 700__ $$aKamalul Aripin, Nurul Fadhilah 000131700 700__ $$aGiacinti-Baschetti, Marco 000131700 700__ $$0(orcid)0000-0003-4416-1036$$aRos, M.
