Synthesis, photophysical properties, and photostability of 9,10-disubstituted anthracenes with fluorine-containing groups (FCG) are described. The values of Φf and λem greatly go up by the meso-substitution with FCG, and a nice corelationship between Φf and Aπ (magnitude of π 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.
