The naphthoate-modifying Cu2Â +-detective Bodipy sensors with the fluorescent ON-OFF performance unaffected by molecular configuration

Two new 8-hydroxyquinoline-Bodipy compounds decorated with naphthoate moiety and therefore different molecular configuration in terms of the dihedral angle between hydroxyquinoline moiety and Bodipy fluorophore were revealed to show similar fluorescence ON-OFF detecting performance to Cu2 +.114
