The receptor 1 was obtained by the condensation reaction of 8 hydroxyjulolidine-9-carboxaldehyde and 1-aminonaphthalen-2-ol
-
with. An 80.6% yield in absolute ethanol (Scheme 2). Receptor 1
was characterized by NMR 1H, spectrometry and ESI-mass, elemental
analysis.? The photophysical properties of 1 with several
.Metal ions using their nitrate salts and of 1eCu2 þ complex with nine anions in methanol were investigated by UVevis fluorescence
measurements,,, And titration studies.
