A series of metal-organic frameworks (MOFs) assembled with diazatetracene (DAT)-based linkers were synthesized and characterized. Despite different chromophore orientations and spacings, photoinduced persistent radicals were generated in all the MOFs, and their spin-lattice relaxation time ( T 1 ) and spin-spin relaxation time ( T 2 ) were found to be relatively long even at room temperature. The generality of long T 1 and T 2 values of photogenerated radicals in the chromophore-assembled MOFs provides a new platform towards quantum sensing applications.
