通过六氯环三磷腈与β-萘酚反应合成了一种新型六（β-萘氧基）环三磷腈化合物，其结构经核磁共振谱、红外光谱和质谱表征。紫外-可见吸收光谱法测定了β-萘酚和六（β-萘氧基）环三磷腈在乙醇、环己烷和乙腈中的最大吸收波长（λmax），并探讨了分子结构和溶剂对吸收光谱的影响。研究发现，溶剂效应对六（β-萘氧基）环三磷腈的吸收光谱无明显影响；六（β-萘氧基）环三磷腈相比β-萘酚最大吸收波长发生蓝移，说明六（β-萘氧基）环三磷腈相比β-萘酚的分子共轭程度降低。

Hexa-(β-naphthyloxy)cyclotriphosphazene is synthesized by the necleophilic substitution reaction of β-naphthol with hexachlorocyclotriphosphazene, which were characterized by NMR, IR, MS and UV-Vis spec-tra. The aximum absorption wavelength (λmax)of the β-naphthol and its derivative in ethanol, hexamethylene and acetonitrile, respectively,were separately determined by UV-Vis spectroscopy. The effects of the solvents and molecular structure on absorption spectra were studied. The results showed that the maximum absorption wave-length (λmax) of hexa-(β-naphthyloxy)cyclotriphosphazene on ultraviolet absorption spectra had not a shift in ethanol, hexamethylene and acetonitrile. Ultraviolet absorption wavelength (λmax) of hexa-(β-naphthyloxy)cyclot-riphosphazene had a blue shift in contrast to that of β-naphthol in acetonitrile, which demonstrated that the molec-ular conjugational effect of hexa-(β-naphthyloxy)cyclotriphosphazene had decreased.
