title: Synthesis of tetraamino derivative of thiacalix[4]arene and its acid-base property studied by UV spectroscopy.
abstract: The tetraamino derivative of thiacalix[4]arene (4) was synthesized and characterized. Its acid-base property in water solution was studied by UV spectroscopy. The pH distribution regions of several acidic or basic species of 4 were determined.
