资源简介：
Two-step reactions of resorcin[4]arene (<b>1</b>) or methylresorcin[4]arene (<b>2</b>) with PPhCl<sub>2</sub> and subsequent <i>in situ</i> oxidation with sulfur powder afforded a series of new thiophosphorylatocavitands <b>1a–1d</b> or <b>2a–2d</b>, respectively. Molecular structures of <b>1a</b>⋅C<sub>3</sub>H<sub>6</sub>O, <b>1d</b>⋅C<sub>3</sub>H<sub>6</sub>O⋅CH<sub>4</sub>O, <b>2a</b>⋅2C<sub>2</sub>H<sub>6</sub>O⋅2H<sub>2</sub>O, and <b>2b</b>⋅2C<sub>4</sub>H<sub>8</sub>O have been determined by X-ray diffraction analysis, which showed the <i>C</i><sub>4v</sub> stereoisomer with the four P = S bonds oriented towards the molecular cavity. The binding ability of thiophosphorylatocavitands <b>1a</b> and <b>2b</b> towards Cu(I), Mn(II), Co(II), Cu(II), and Zn(II) halides was studied by UV/vis absorption.
