Multiresponsive chromic soft materials: formation of macrocycles from carbazole-based biradicaloids Ruiz-Delgado, María del Carmen Espectroscopia molecular - Congresos -conjugated biradical compounds become essential building blocks in DCC (dynamic covalent chemistry).1 This field is based on the creation of structural scaffolds based on chemical components which interact through strong but reversible bonds. Importantly, dynamic covalent bonds will be at the center of attention because of their unique feature to become reversible under mild conditions.2 Recently, we have demonstrated the reversible interconversion between a stable quinoid precursor based on a para-substituted carbazole with terminal dicyanomethylene groups and a macrocycle cyclophane upon soft external stimuli (temperature, pressure, light), which results on strong chromic features.3 In this work, we investigate the interconversion of the monomer/cyclophane transformation in carbazole-based systems, both in solution and solid state, upon external stimuli. To this end, we use a combined experimental and theoretical study that links vibrational spectroscopy (Raman and IR) with DFT calculations. 2018-09-06T06:52:22Z 2018-09-06T06:52:22Z 2018-09 2018-09-06 conference output https://hdl.handle.net/10630/16405 eng 25th International Conference on High Resolution Molecular Spectroscopy Bilbao 3 Septiembre 2018 http://creativecommons.org/licenses/by-nc-nd/4.0/ open access Attribution-NonCommercial-NoDerivatives 4.0 Internacional
