Dioxa[3.3](3,6)carbazolophane 1 has been synthesized by the cyclizatio
n reaction between 3,6-bis(hydroxymethyl)carbazole and corresponding d
ibromide. The transannular pi-pi electronic properties of 1 in solutio
n were examined by absorption and emission spectra. The structure of 1
was confirmed by X-ray crystal analysis.
