The objective of this invention is to provide fluorescent compounds comprising a naphthalene skeleton, an electron donating group substituted at the 2- or 1-position of the naphthalene skeleton, and an electron attractive group substituted at the 6- or 4-position of the skeleton. The fluorescent compound of this invention is capable of emitting visible light having a desired color by choosing an appropriate combination of the electron donating group A, which has an electron-pushing function, and the electron attractive group B, which has an electron-pulling function.
本发明的目的是提供包含
萘骨架、电子给体基团取代在
萘骨架的2-或1-位置以及电子吸引基团取代在骨架的6-或4-位置的荧光化合物。本发明的荧光化合物能够通过选择具有电子推动功能的电子给体基团A和具有电子拉拽功能的电子吸引基团B的适当组合来发射具有所需颜色的可见光。
