A novel class of photoactive compounds has been synthesized by combining the classicalo-nitrobenzyl scaffold with an environmentally sensitive dye, 4-amino-nitrobenzothiazole. Irradiation in a polar solvent led to an excited state that was inoperative for photochemistry whereas excitation in a nonpolar solvent led to an excited state that was photochemically active. While our design hypothesis tests true for the on/off control of a photochemical process, an alternative photochemical ring-opening of the heterocycle appears to be the preferred process in contrast to the intended photocleavage process.</dc:description> <dc:identifier>https://aperta.ulakbim.gov.trrecord/8053</dc:identifier> <dc:identifier>oai:zenodo.org:8053</dc:identifier> <dc:rights>info:eu-repo/semantics/openAccess</dc:rights> <dc:rights>http://www.opendefinition.org/licenses/cc-by</dc:rights> <dc:source>CHEMISTRYSELECT 5(23) 7016-7020</dc:source> <dc:title>The Malleable Excited States of Benzothiadiazole Dyes and Investigation of their Potential for Photochemical Control</dc:title> <dc:type>info:eu-repo/semantics/article</dc:type> <dc:type>publication-article</dc:type> </oai_dc:dc>
