In this paper, we describe the effective synthesis of oxatruxene and its photophysical, electrochemical and structural features that transpire when a methylene unit in a truxene core is replaced by an oxygen atom to yield 5-oxatruxene. This modification broke the C_3h symmetry and at the same time introduced a more electronegative structure as revealed by a four-fold increase in the quantum yield as compared to truxene. The derivatives of this material have great potential in optoelectronic devices and in organic photovoltaics. This proposed new synthetic method can be used to introduce other heteroatoms into the truxene system.

有效合成5-氧杂a烯以及氧杂原子对其物理化学性质的异常影响†

在本文中，我们描述了氧杂tru烯的有效合成及其光物理，电化学和结构特征，当戊烯核中的亚甲基单元被氧原子取代以生成5-氧杂tru烯时，其发生蒸腾。这种修饰破坏了C _3h的对称性，同时引入了更多的负电性结构，这与量子通量相比，量子产率提高了四倍。这种材料的衍生物在光电器件和有机光伏中具有巨大的潜力。该提出的新的合成方法可用于将其他杂原子引入戊二烯体系。
