In this research, pyreno[4,5‐c:9,10‐c′]difuran and its analogues have been successfully synthesized through a one‐step reaction using the same precursor and their physicochemical properties were studied. UV/Vis, fluorescence and CV measurements illustrated that the inserted chalcogen atoms (O, S and Se) brought almost no change on the photochemical and electrochemical properties whereas TM‐2N‐CH₃ exhibited more blue‐shifted fluorescence emission and simultaneously elevated HOMO energy level.

直接访问取代的Pyreno [4,5-c：9,10-c']二呋喃及其类似物的直接方法

在这项研究中，吡喃并[4,5-c：9,10-c']二呋喃及其类似物已通过一步反应使用相同的前体成功合成，并对其理化性质进行了研究。UV / Vis，荧光和CV测量表明，插入的硫属元素原子（O，S和Se）几乎没有改变光化学和电化学性质，而TM-2N-CH ₃表现出更多的蓝移荧光发射，同时HOMO能量升高等级。
