title: Photoresponsive host-guest systems based on a new azobenzene-containing cryptand.
abstract: A new azobenzene-bridged cryptand was synthesized; it can be well controlled between cis and trans isomers by irradiation with different wavelengths or by being heated. It was found that this cryptand exhibits an ON-OFF binding ability with 2,7-diazapyrenium (DAP) derivatives. It binds DAP derivatives as the cis isomer only, as demonstrated by various methods. The fluorescence property of DAP derivatives endows these host-guest systems with detectable fluorescent output signals, which makes monitoring these photoresponsive systems convenient.
