The present invention relates to a novel fluorene derivative having a structure of formula (I): wherein X is independently selected from a group consisting of Cl, Br, I, trifluoromethanesulfonate and 4-(trifluoromethyl)benzenesulfonate; Y is a group of formula-(CH2)n- where n is an integer ranging from 3 to 12; and R1, R2, R3, and R4 are independently selected from a group consisting of tert-butyl group, triphenylamine, carbazole and carbazole derivative. The invention further relates to a polymer obtained from the said novel fluorene derivative and methods for preparing the same, as well as their uses as materials for an organic light-emitting diode device.
