N-(2-Anthryl)-2-[bis(pentafluorophenyl)boryl]benzylideneamine changed its fluorescence color from yellow to green upon addition of an equimolar amount of cyanide ion, in contrast to the N-phenyl derivatives, which showed quenching of the emission. Theoretical calculations suggested that switching of the imine-based emission to anthryl-based emission by adduct formation provides the N-anthrylimine derivative with the fluorescence color change.
在加入等摩尔量的氰离子后,N-(2-蒽基)-2-[双(五氟苯基)硼烷基]苯亚胺的荧光颜色由黄色变为绿色,而 N-苯基衍生物的荧光颜色则发生了淬灭。理论计算表明,N-蒽基亚胺衍生物的荧光颜色变化是通过加合物形成将亚胺基发射转换为蒽基发射实现的。
