Different optical responses of OFPs that alter either absorption, fluorescence, or chemiluminescence. (a) Schematic depiction and (b) structural formula of exemplary OFPs. DABBF is a scissile, reversible OFP that becomes blue colored upon activation. [17] Anthracene‐maleimide Diels‐Alder adducts are scissile, quasi‐static OFPs that can either turn “on” their fluorescence or are dual‐fluorescent. [18] Dioxetanes are scissile, quasi‐static, mechanoluminescent OFPs. [11] Note that force‐induced transitions can be either scissile or non‐scissile as indicated by the dashed lines in (a). Dashed lines in (b) indicate the attachment points to the macromolecular framework.
