contrasting colorchanges in solution and the solid state. Besides, many of the derivatives exhibit partial phase transition upon UV irradiation. The highlight of this class of photoswitches is the reversible light-induced phase transition between solid and liquid phases in the parent compound, which can be used in patterned crystallization. These results show that this new class of azoheteroarene based photoswitches

Abstract A convenient synthetic route is reported for the preparation of aroyl substituted triazinones and triazinono-xathiazinedioxides by the interaction of chlorosulfonylisocyanate and phenylhydrazones (derived from acetylacetone, 1-benzoylacetone and dibenzoylmethane).

procedure was employed to prepare a novel series of pyridine glycosides. The protocol allows the reaction of 2-pyridone with 1,2,3,4,6-penta-O-acetyl-α-D-glucopyranose under solvent-free microwave-assisted synthesis using different solid supports. Silica gel has been found to be an efficient and environmentally friendly promoter. Structures of the new products were confirmed based on their elemental analyses
The photo-responsive host-guest interaction of an azo-based photoswitch with permethylated cyclodextrin is used to modulate the dynamic covalent interaction of a phenyl boronic acid and D-fructose by irradiation with light.
