Provided is an inexpensive and high-performance dye compound that does not use an expensive precious metal and does not require the use of a strong electron-withdrawing group. The compound is formed such that a boron substituent is introduced into a heteroatom-containing π electron-based backbone containing a double bond between carbon and the heteroatom to obtain a compound in which a backbone having boron and a coordination bond in a molecule thereof is used as a π electron-accepting backbone.
本发明提供了一种廉价且高性能的
染料化合物,它不使用昂贵的贵
金属,也不需要使用强吸电子基团。该化合物是这样形成的:将
硼取代基引入到含有π电子的杂原子骨架中,该骨架含有碳和杂原子间的双键,从而得到一种化合物,其中具有
硼的骨架及其分子中的配位键被用作π电子接受骨架。
