The photostability of aromaticcompounds in the presence of air is significantly improved through perfluoroalkylation of the corresponding aromatic cores and use of polyfluorinated solvents despite higher O(2) concentration in polyfluorinated solvents than in hydrocarbon solvents.

A highly stable metal–organicframework, [Fe3(ACTBA)2}X·6DEF]n (1; X = monoanion), based on trinuclear iron(III) secondarybuildingunits connected by tetracarboxylates with an anthracene core, 2,6,9,10-tetrakis(p-carboxylatophenyl)anthracene (ACTBA), is reported. Depending on the direction of light polarisation, crystals of 1 exhibit anisotropic optical properties with birefringence Δn = 0.3 (λ =

A mildselective protocol was used to prepare tetrakis(2-chlorophenylthio)anthracene from tetrabromoanthracene and sodium 2-chlorobenzenethiolate avoiding the thiolate self-attack. The uncatalyzed nucleophilic substitution of a series of mono-, di-, and tetrabrominated arenes by arylthiolate ions was attempted in mild conditions to investigate the scope of the substitution reaction regarding the size
