The invention discloses a novel 1,8-carbazole derivative, a preparation method and an optical device of using the carbazole derivative, wherein the 1,8-carbazole derivative has the following general formula structure as shown in the secification. Eectrondrawing groups are formed at the 1st and 8th bits of the carbazole derivative, and alkyls are formed at the 3, 6 and 9 bits. Thus, synthesis of 1,8-dibasic carbazole is achieved. The generating probability of an excitor can be effectively increased by the carbazole derivative, the luminous efficiency of the device is effectively improved, and the 1,8-carbazole derivative can be widely applied to the field of organic electroluminescence. |
