This work examines a family of MOFs that are colourimetric sensors to acid and base vapours.With the strongest colour change associated with strong base vapours such as ammonia,this material can act as an ammonia sensor for applications in health and safety.A methyl red based linker is ...

Crystallise it by dissolving in it AcOH and adding pet ether (b 40-50o) to give colourless plates. UV max (A 1mm ): 222nm (865) and 268nm (116) [Isler et al. Helv Chim Acta 40 1242 1957]. [Beilstein 16 IV 977.] Methyl (triphenylphosphoranylidene)acetate Preparation Products And...
Plants that have been attacked by aphids release volatile compounds to elicit airborne defence (AD) in neighbouring plants2,3,4,5. However, the mechanism underlying AD is unclear. Here we reveal that methyl-salicylate (MeSA), salicylic acid-binding protein-2 (SABP2), the transcription factor ...
