We report the synthesis and photochemical and photophysical properties of double alkylene-strapped 9,10-diphenylanthracene derivatives 3a–c (a: C6 strap, b: C7 strap, c: C8 strap) in which the reactive central aromatic ring of the anthracene moiety is protected by the double alkylene straps. Thus, 3a–c were much more resistant to photochemical reactions than the parent 9,10-diphenylanthracene (DPA)
我们报告了双亚烷基链的9,10-二苯基蒽衍生物3a – c(a:C6链带,b:C7链带,c:C8链带)的合成,光化学和光物理性质,其中蒽部分具有反应性中心芳香环由双亚烷基带保护。因此,3a - c对光化学反应的抵抗力比其母体9,10-二苯基蒽(DPA)强。此外,C 6 H 12和流延膜中的3b和粉末状态在3a,3b中显示出最高的荧光量子产率,四重三乙基甲硅烷基保护的DPA 4和DPA,其中3b中的C7带有效地阻止了荧光的自猝灭。
