1,4-Diarylpentiptycenes (1a-e) were synthesized from 1,4-dichloro- or 1,4-difluoro-2,5-diarylbenzene derivatives by double base-promoted dehydrohalogenation to give corresponding arynes, which in the presence of anthracene undergo cycloaddition providing 1,4-diarylpentiptycenes in moderate overall yields. The resulting 1,4-diarylpentiptycenes show fluorescence modulated by the 1,4-aryl residues. The
由1,4-二氯-或1,4-二氟-2,5-二芳基苯衍生物通过双碱促进的脱卤化氢合成相应的芳烃,在蒽的存在下进行合成,从而合成1,4-二芳基五肽(1a-e)环加成以适中的总收率提供1,4-二芳基戊二烯。所得的1,4-二芳基戊二烯显示由1,4-芳基残基调节的荧光。在硝基芳族化合物蒸气的存在下,荧光被猝灭,这表明其在爆炸物检测中的潜在应用。
