trimethylsiloxymethylene- and pentafluorophenoxymethylene-) as well as with an additional azobenzene unit were successfully obtained. The photoisomerizationbehaviors of the synthesized azo dyes were investigated in solution as well as in films. Importantly, the occurrence of photoisomerization (at least near the surface after UV treatment) was confirmed in the crystalline dye films. The resulting compounds can be

A tetrabutylammonium hydrogen sulfate (TBA-HS) mediated procedure for one pot synthesis of novel benzopyran-annulated pyrano[2,3-c]pyrazoles via domino/Knoevenagel-hetero-Diels–Alder reaction has been demonstrated.
