para-Substituted salicyldialdehydes are versatile molecular building blocks for porous organic cages, fluorescent dyes, spirobenzopyrans, homooxacalixarenes, dinuclear metal complexes, macrocycles, and cryptands. To date, no procedures for the synthesis of para-aryl-substituted salicyldialdehydes have been reported, which would broaden the scope of the above-mentioned topics, especially in the field
and characterized, and their coordinationproperties were examined along the lanthanideseries through speciation studies with NMR and ESI-MS. Well-defined tetranuclear complexes are formed with both ligands, but their stabilities with heavier lanthanides are considerably reduced, especially for complexes with L3. This is attributed to a destabilizing effect of pending PEG arms in combination with

A new anion binding motif based on triptycene core has been synthesized from 2,7,14-trinitrotriptycene. Its well-defined binding pocket allowed for the selective recognition and sensing of dihydrogenphosphate in DMSO-d6 + 0.5% H2O.
