For the solution process blue fluorescent material, tertiary butyl (T) and anthracene (A) were first introduced as substituents to TAT core part, 2-tert-butyl-9,10-bis(3”,5”diphenylbiphenyl-4’-yl)anthracene (T-TAT) and 2-(9-anthracenyl)-9,10-bis(3”,5”-diphenylbiphenyl-4’-yl)anthracene (A-TAT). All three materials indicated typical absorption band of anthracene in the range of 350 to 400 nm. T-TAT exhibited similar optical properties to TAT, but A-TAT has longer absorption and PL emission compared to other two compounds. In case of spin-coated film, A-TAT exhibited absorption maximum value of 408 nm and photoluminescence maximum value of 469 nm. T-TAT and A-TAT can be applicable to solution process as a blue fluorescence material. |
