Anthracene-based compounds that undergo photocycloaddition have garnered extensive attention for the fabrication of light-responsive crystalline materials. Nevertheless, their solid-state photocycloaddition mechanism remains elusive. Herein, transient absorption spectroscopy combined with theoretical calculations was e...

Compact naphthalimide-based donor–acceptor–radical triads, together with their corresponding radical-free donor–acceptor dyads, were prepared as a tunable platform for manipulating long-lived excited-state spin dynamics in closely coupled organic multispin systems. Structural analysis and DFT calculations support a com...

Polymorphism in covalent organic frameworks (COFs) offers a unique platform to decipher structure-property relationships, yet its impact on excited-state dynamics remains unexplored. Herein, we construct two chemically identical but topologically distinct 1D and 2D COF polymorphs to correlate framework architecture wit...
