Novel synthesis and the photochromic properties of 1,2-dicyano[2.n]metacyclophan-1-enes are reported. The intramolecular cyclization of bis(cyanomethyl)arenes successfully afforded 1,2-dicyano[2.n]metacyclophan-1-enes in good yield. The obtained cyclophanes show photochromism and the lifetime of the colored form is dependent on the chain length (n).
1,2-二氰基[2.]的新型合成及其光致变色性质。报道了n ]个环环-1-烯。双(氰甲基)芳烃的分子内环化成功提供了1,2-二氰基[2]。n ]间环潘-1-烯具有良好的收率。所获得的环烷显示出光致变色,并且有色形式的寿命取决于链长(n)。
