The triphenyltin and tri-n-butyltin complexes of some 5-[(E)-2-(aryl)-1-diazenyl]-2-hydroxybenzoic acids have been synthesized and characterized by 1H-, 13C-, 119Sn-NMR, IR and 119mSn Mössbauer spectroscopic techniques in combination with elemental analysis. The crystalstructures of triphenyltin 5-[(E)-2-(aryl)-1-diazenyl]-2-hydroxybenzoates (aryl=phenyl, 2-methylphenyl, 3-methylphenyl and 4-methoxyphenyl)

Photocontrolled reversible room temperature phosphorescence (RTP) emission engendered by the complexation of β-cyclodextrin (β-CD) and α-bromonaphthalene (α-BrNp) can be employed to address the threading and dethreading of the pseudorotaxane formed between β-CD and sodium 2-hydroxy-5-((4-nitrophenyl)diazenyl)benzoate (DAYR) in the ternary system in aqueous solution.
