Meso-disubstituted anthracenes with fluorine-containing groups: synthesis, light-emitting characteristics, and photostability.
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 an excellent ability in the photostability as well as in the emission efficiency.
