Two pure hydrocarbon molecules of l,3,5-tris（9-phenyl-9H-fluoren-9-yl）benzene（mTPFB）and l,3,5-tris（2-tert-butyl-9-phenyl-9H-fluoren-9-yl）benzene（tBu-mTPFB）were synthesized.Due to the conjugation blocked connection mode and rigid/bulky substitutions,these two materials possess high triplet energy,enabling them as good hosts for blue phosphor in PhOLEDs.By studying their thermal,electrochemical,electronic absorption and photoluminescent properties,it was found that the influence of the inert tert-...
