Sodium-based donor-acceptor assemblies featuring thermally activated delayed fluorescence enabled by highly efficient through-space charge transfer.

ABSTRACT: Exploring more economical and innovative alternatives to precious 4d and 5d metal complexes used in photocatalysis, OLEDs, or energy conversion has primarily focused on 3d metals, leaving highly abundant alkali metals underexplored. We show that, under stoichiometry control of 1,10-phenanthroline-5-carbonitrile (^CNphen) and sodium 2,6-bis(trimethylsilyl)benzenethiolate Na(^TMSBT), sodium complexes can be obtained that either form the neutral linear assembly [Na(THF)(^CNphen)(^TMSBT)]_N (Na1D) or {[Na(^CNphen)₄](^TMSBT)}_N (Na2D) as a 2D-polymeric arrangement with octahedrally coordinated Na, similar to 18 valence electron transition metal complexes, and the thiolate acting as a counter anion.
