The incorporation of a flexible one-dimensional alkyl chain in the chromophore backbone drastically accelerates by more than one order of magnitude the sensing dynamics for the detection of 2,4-dinitrotoluene (DNT) vapors. %G English %2 https://univ-rennes.hal.science/hal-02438559/document %2 https://univ-rennes.hal.science/hal-02438559/file/Malval_et%20al_Porosity-driven%20large%20amplitude%20dynamics_accepted.pdf %L hal-02438559 %U https://univ-rennes.hal.science/hal-02438559 %~ UNIV-RENNES1 %~ CNRS %~ INSA-RENNES %~ ENSC-RENNES %~ UNIV-STRASBG %~ ISCR %~ SCR_OMC2012 %~ ISCR-OMC %~ ISCR-CSM %~ STATS-UR1 %~ UR1-SPM %~ INC-CNRS %~ UR1-UFR-SPM %~ UR1-HAL %~ UR1-SDLM %~ TEST-UR-CSS %~ SITE-ALSACE %~ UNIV-RENNES %~ INSA-GROUPE %~ TEST-HALCNRS %~ UR1-MMS %~ TEST2-HALCNRS %~ LABORATOIRES-UHA %~ UHA %~ IS2M
