Weder, Christoph 2016-03-18 Multiresponsive materials that display predefined photoluminescence color changes upon exposure to different stimuli are attractive candidates for advanced sensing schemes. Herein, we report a cyano-substituted oligo(p-phenylene vinylene) (cyano-OPV) derivative that forms five different solvent-free solid-state molecular assemblies, luminescence properties of which change upon thermal and mechanical stimulation. Single-crystal X-ray structural analysis suggested that tolyl groups introduced at the termini of solubilizing side-chains of the cyano-OPV play a pivotal role in its solid-state arrangement. Viewed more broadly, this report shows that the introduction of competing intermolecular interactions into excimer-forming chromophores is a promising design strategy for multicolored thermo- and mechanoresponsive luminescent materials. application/pdf https://folia.unifr.ch/global/documents/304665 https://folia.unifr.ch/documents/304665/files/fro_tmc.pdf https://folia.unifr.ch/documents/304665/files/fro_tmc_sm.pdf eng info:eu-repo/semantics/altIdentifier/doi/10.1002/chem.201600272 info:eu-repo/semantics/openAccess License undefined Chemistry - A European Journal. - 2016, vol. 22, no. 13, p. 4374–4378 materials science mechanoresponsive luminescence sensors supramolecular chemistry thermoresponsive luminescence info:eu-repo/classification/udc/54 A Thermo‐ and mechanoresponsive cyano‐substituted oligo(p‐phenylene vinylene) derivative with five emissive states http://purl.org/coar/resource_type/c_6501
