Compounds with strong absorptions in the ultraviolet (UV) region of the spectrum, particularly the UVA and UVB, have seen much interest as UV screeners or absorbers in a wide variety of commercial products. A series of benzisoxazole 2‐oxides have been synthesized and characterized by UV–vis spectroscopy. A number of derivatives have been shown to posses moderate to strong molar absorption coefficients
在光谱的紫外线(UV)区域具有强吸收性的化合物,尤其是UVA和UVB,已成为许多商业产品中作为UV屏蔽剂或吸收剂引起了极大兴趣。已经合成了一系列苯并异恶唑2-氧化物,并通过紫外可见光谱进行了表征。已显示许多衍生物在UVB范围内(约300 nm)具有中等至强的摩尔吸收系数,其中最强的是衍生自二苯甲酮的衍生物。其他三个含有其他吸电子基团的衍生物在UVA中(约340 nm)显示出很强的摩尔吸收系数。在父衍生物溶剂效应显示出与在λ小变化的摩尔吸光系数的变化最大价值观。对这些化合物作为防止聚苯乙烯光氧化的潜在添加剂的初步研究表明,母体未取代的苯并异恶唑2-氧化物化合物最有效地抑制了聚合物的降解。版权所有©2013 John Wiley&Sons,Ltd.
