1) based on [Zn (COO) ] SBU. The exposed naphthalene
3 6
moieties make 1 highly emissive and allow detection of
electron-deficient nitro explosives in aqueous media, where
metal-bound urotropine also plays its part. It seems promising
to judiciously extend and improve the strategy adopted herein
to obtain even better sensors for explosives for real-time
monitoring. The axially bound urotropine molecules can take
part nicely as a heterogeneous catalyst in the Baylis−Hillman
reactions between MVK and substituted benzaldehydes
affording satisfactory isolated yields. Moreover, the catalyst is
easily recovered and recycled without loss in activity up to four
cycles at least. Interestingly, compound 1 shows a heteroge-
neous pillar insertion reaction of azp linker to afford a 3D MOF
