Abstract:
We examine the ability of hydrostatic pressure to directly influence intra- and intermolecular distances and chiral organisation. We investigate pressure-responsive circularly polarised luminescence in optically active europium complexes doped with axially chiral 2,2'-bis(diphenylphosphino)-1,1'-binaphthyl and point-chiral (R,R)-(-)-2,3-bis(tert-butylmethylphosphino)quinoxaline ligands. A new molecular design strategy for pressure-responsive sensing materials is described.

Conjugated systems containing an even number of π-electron pairs undergo a conrotatory ring closure. For example, thermal electrocyclization of (2E,4E)-2,4-hexadiene, a conjugated diene containing two π-electron pairs, gives trans-3,4-dimethylcyclobutene.
