Abstract
Our research group have reported that, under high dilution conditions, condensation reactions between 4,4’-ethylenebis(2,6-morpholinedione), 1, and aromatic diamines gave a new series of tetraaza chelating cylophanes, which have amide and aromatic groups in the ring framework and pendant carboxymethyl groups [1].[...]

The emission spectra were recorded on a Perkin Elmer LS-50 spectrofluorometer
The electrospray ionization (ESI) mass spectra were obtained by the use of a JEOL HX 110A
Summary
Our research group have reported that, under high dilution conditions, condensation reactions between 4,4’-ethylenebis(2,6-morpholinedione), 1, and aromatic diamines gave a new series of tetraaza chelating cylophanes, which have amide and aromatic groups in the ring framework and pendant carboxymethyl groups [1]. Spectroscopic Measurements The solution electronic spectra were obtained by the use of a Perkin-Elmer Lambda 2 UV-vis spectrometer. The emission spectra were recorded on a Perkin Elmer LS-50 spectrofluorometer.
