摘　　要：通过缩合反应合成了一种有机紫外滤波染料-2,7二甲基-3,6-偶氮环庚-1,6-二烯高氯酸盐,并采用元素分析、红外光谱、紫外光谱等手段对其进行表征,着重讨论了不同浓度的染料溶液和染料掺杂的聚乙烯醇(PVA)薄膜的紫外光谱性质。实验表明,当染料浓度较低时,溶液的最大吸收波长为322 nm,薄膜的最大吸收波长为325 nm。随着染料浓度的增加,溶液和PVA膜紫外截止通带宽度加宽,表现为285～345 nm区间为强吸收带,而在日盲紫外波段(240～285 nm)保持较高的透过率。利用染料溶液和染料掺杂的PVA膜的这种光谱特性,制作出日盲紫外滤波器。The dye 2,7-dimethyI-3,6-diazacyclohepta-1,6-diene perchlorate was prepared by condensation reaction and characterized by elemental analysis, infrared spectroscopy and UV-visible techniques. The influences of dye solution and dye-doped polyvinyl alcohol （PVA） film with different concentrations on the property of UV spectroscopy were mainly investigated. Optical transmission spectra indicate that maximum absorption peaks for dye solution and dye-doped PVA film feature at 322 nm and 325 nm, respectively. With increasing dopant concentration, dye solution and dye-doped film exhibit strong absorption at cut-off region （285-345 nm） and are high transmissive at solar blind spectral region （240-285 nm）. The sample composed of dye solution or dye-doped film, inorganic crystal and coloured glass as solar blind filter was demonstrated.
