Abstract

In this study, firstly a novel thiacalix[4]arene functionalized
from the phenolic oxygen side was synthesized. Then a series of dyes were
synthesized by linking the heterocyclic groups to the novel thiacalix[4]aren
through a diazo reaction. The azo dyes were characterized by UV-vis, FT-IR and ¹H-NMR
spectroscopic techniques. Effect
of solvent and effect of acid-base upon the absorption spectra of the azo dyes
were investigated.
