摘要

Two bis–bis(urea) ligands (L¹ and L²) incorporating the photoactive 9,10-diphenylanthracene fragment were designed for the construction of anion-coordination-driven assemblies and subsequent oxygenation of anthracene moieties for singlet oxygen storage. The corresponding A₂L₂-type sulfate complexes [TEA]₄[(SO₄)₂(L¹)₂] (1) and [TEA]₄[(SO₄)₂(L²)₂] (2), where TEA = tetraethylammonium, were achieved by coordinating the ligands L¹ or L² with sulfate anions. Both 1 and 2 were able to undergo [4 + 2] photooxygenation to form endoperoxide photoproducts 1-EPO and 2-EPO, which can be partially converted back to the original anthracene compounds after heating. The structures of 1-EPO and 2-EPO were unambiguously confirmed by X-ray crystallography, NMR and UV–vis spectroscopy, and high-resolution electrospray ionization mass spectrometry.
