Summary, etc. <p style="text-align: justify;">Some new compounds 9-(1-aryl-5-methyl-1<em>H</em>-1,2,3-triazol-4-yl)-6-hydroxy-3<em>H</em>-xanthen-3-one <strong>7a</strong><strong>-j</strong> have been synthesized for new fluorescence probe material. Their fluorescence and ultraviolet-visible spectra have been studied. Their structures are established by MS, IR and <sup>1</sup>H NMR spectral data. The structure of title compound <strong>7c</strong> has been identified by X-ray diffraction. C<sub>22</sub>H<sub>14</sub>C1N<sub>3</sub>O<sub>3</sub>, belongs to triclinic system, space group <em>P</em>ī with <em>a </em>= 8.296(4), <em>b </em>= 9.726(5), <em>c </em>= 11.976(6) Å, <em>α</em> = 90.953(7), <em>β</em> = 105.081(7), <em>γ</em> = 100.693(8)º, <em>V </em>= 914.7(8)Å<sup>3</sup>, <em>Z </em>= 2, <em>Dc </em>= 1.466 Mg/m<sup>3</sup>, <em>F</em>(000) = 416.0 and <em>μ </em>= 0.240 mm<sup>–1</sup>. The title compound has a weaker inhibiting HIV-1 protease than indinavir.</p>
