Synthesis, photophysical properties, and photostability of 9,10-disubstituted anthracenes with fluorine-containing groups (FCG) are described. The values of phi(f) and lambda(em) greatly go up by the meso-substitution with FCG, and a nice corelationship between phi(f) and A(pi) (magnitude of pi conjugation length in the excited single state) is observed. The C6F5 group at the meso positions exhibits
描述了具有含氟基团(FCG)的9,10-二取代蒽的合成,光物理性质和光稳定性。通过用FCG进行介观取代,phi(f)和lambda(em)的值大大提高,并且phi(f)和A(pi)之间的良好相关性(在激发单态下pi的共轭长度的大小)为观察到的。在中间位置的C6F5基团在光稳定性以及发射效率方面显示出优异的能力。
