Using this approach we demonstrate a new means to tuning DASA based photoswitches by increasing the energy of the closed form relative to the open form. To highlight the potential of this approach a new DASA derivative bearing a methyl substituent on the 5-position of the triene was synthesized and the effect of this substitution was studied using 1H NMR spectroscopy, time-dependent UV-Vis and solvatochromic analysis. The new DASA derivative shows a higher dark equillibrium, favoring the open form, and drastically faster thermal recovery than the unsubstituted derivative with the same donor and acceptor."}],"intvolume":"        58","language":[{"iso":"eng"}],"OA_type":"green","type":"journal_article","external_id":{"pmid":["35075464"]},"status":"public","author":[{"last_name":"Peterson","full_name":"Peterson, Julie A.","first_name":"Julie A."},{"full_name":"Stricker, Friedrich J","id":"7aca2cfc-46cf-11f0-abd3-8c96b5186745","first_name":"Friedrich J","last_name":"Stricker"},{"last_name":"Read de Alaniz","first_name":"Javier","full_name":"Read de Alaniz, Javier"}],"date_updated":"2026-05-18T09:46:30Z","pmid":1,"publication":"Chemical Communications","quality_controlled":"1","citation":{"mla":"Peterson, Julie A., et al. “Improving the Kinetics and Dark Equilibrium of Donor-Acceptor Stenhouse Adduct by Triene Backbone Design.” <i>Chemical Communications</i>, vol. 58, no. 14, Royal Society of Chemistry, 2022, pp. 2303–06, doi:<a href=\"https://doi.org/10.1039/d1cc06235b\">10.1039/d1cc06235b</a>.","short":"J.A.
