Photoresponsive Crown Ethers. Part 18. Photochemically 'Switched-on' Crown Ethers Containing an Intra-annular Azo Substituent and their Application to Membrane Transport

Photoresponsive crown ethers (3) having an intra-annular azo substituent have been synthesized.These crown ethers have been designed so that the crown-metal interaction can only occur upon photoisomerisation of the intra-annular azo substituent from trans
