Disclosed is a novel benzoxazole derivative which has high excitation energy, particularly high triplet excitation energy, and is a bipolar substance. A benzoxazole derivative represented by the following General Formula (G1) is provided.
In the formula, R1 and R2 independently represent a hydrogen atom, an alkyl group with 1 to 4 carbon atoms, or a substituted or unsubstituted aryl group with 6 to 13 carbon atoms, substituents of the substituted aryl group may be bonded to form a ring which may form a spiro ring structure, R11 to R14 independently represent a hydrogen atom, a halogen, an alkyl group with 1 to 4 carbon atoms, or an unsubstituted aryl group with 6 to 10 carbon atoms, a bond formed between any two of α, β, and γ forms a carbazole skeleton, and n is 0 to 3.
揭示了一种新的苯并噁唑衍生物,具有高激发能量,特别高的三重激发能量,并且是一种双极性物质。提供了以下通用公式(G1)表示的苯并噁唑衍生物。在该公式中,R1和R2独立表示氢原子,具有1至4个碳原子的烷基基团,或具有6至13个碳原子的取代或未取代芳基基团,取代芳基基团的取代基可以结合形成一个环,该环可以形成螺环结构,R11至R14独立表示氢原子,卤素,具有1至4个碳原子的烷基基团,或具有6至10个碳原子的未取代芳基基团,α,β和γ中的任意两个之间形成的键形成一个咔唑骨架,n为0至3。
