Description

We have prepared crownocarbazolophanes, whose fluorescence was changed in the presence of metal ions. Here, we synthesized carbazole imine cyclophane (2n) and the emission behavior in the presence of metal ions was investigated. The structures of (2n) were identified by NMR, MS and elemental analysis. In the proton NMR spectrum of (2n), H1, H2, and H4 in carbazole ring shifted upfield compared with those of the reference, suggesting that two carbazole rings in (2n) are situated in partially overlapped geometry. Fluorescence spectra of (2n) were monomer-like emission. In the presence of metal ions, monomer-like emission was generally quenched, while in the presence of zinc and cadmium ions, new fluorescence shifted to longer wavelength appeared.
