Teki et al. describe how transient absorption measurements performed on pentacene derivatives with stable radical substituents in dilute solution demonstrate that the ultrafast formation of a triplet excited state in the pentacene moiety (violet) from a photoexcited singlet state (green) occurs through contributions of enhanced intersystem crossing and singlet fission.<boxed-text content-type="graphic" position="anchor" orientation="portrait"><graphic position="anchor" mimetype="image" xlink:href="ark:/27927/pghmfnfd61" orientation="portrait" xlink:type="simple" xmlns:xlink="http://www.w3.org/1999/xlink" /></boxed-text></p> </abstract>
