Abstract
Bis-crown-containing styryl dyes (E,E)-2a,b having the structure and properties of molecular pincers were synthesised. In acetonitrile solution, dye (E,E)-2b is able to form intramolecular sandwich complexes with Ca2+ and Ba2+ cations. These complexes undergo E–Z-photoisomerisation and intramolecular stereoselective [2+2]-photocycloaddition to afford cyclobutane derivatives 6a,b, whose structures were studied by 1H NMR spectroscopy. Molecular-mechanics and semiempirical quantum-chemical calculations were performed to interpret experimental data.
