Fast Isomerizing Methyl Iodide Azopyridinium Salts for Molecular Switches Jaume Garcia-Amorós Walter A. Massad Santi Nonell Dolores Velasco 10.1021/ol1013679.s001 https://acs.figshare.com/articles/journal_contribution/Fast_Isomerizing_Methyl_Iodide_Azopyridinium_Salts_for_Molecular_Switches/2745349 The usefulness of azopyridinium methyl iodide salts for designing new promising light-controlled molecular switches is presented. Large absorbance changes have been produced in the samples by irradiation with light at λ = 355 nm. The thermal recovery of the initial state took place completely within 130−450 ms, which is much faster than that reported previously for other push−pull azobenzene-doped nematic mixtures. 2010-08-06 00:00:00 irradiation sample mixture usefulness Large absorbance changes Molecular Switches nematic Fast Isomerizing Methyl Iodide Azopyridinium Salts azopyridinium methyl iodide salts 355 nm recovery
