Since the conventional electron transporters have low thermal stability, the organic electroluminescent devices using them are not sufficient in terms of the compatibility of their luminance and luminous efficiency with device lifetime.
A 1,3,5-triazine derivative of formula (1) is obtained by a metal catalyst-aided coupling reaction of a compound of formula (2) with a compound of formula (3), and this is used as a composing component of an organic electroluminescent device.
[In the formulae, Ar1 and Ar2 represent phenyl group or the like, R1 and R2 represent hydrogen atom or the like, R3 represents methyl or the like, m is an integer of 0 to 2, X represents 2,4-pyridylene or the like, p is 1 or 2, a and b are 1 or 2, a+b is 3, q is 0 or an integer of p or less, M represents —MgR4 group or the like, R4 represents chlorine atom or the like, r is p-q, and Y represents a leaving group.]
由于传统的电子传输体的热稳定性较低,使用它们的有机电致发光器件在亮度和发光效率与器件寿命的兼容性方面不足。式(1)的1,3,5-三嗪衍生物是通过式(2)的化合物与式(3)的化合物的金属催化偶联反应获得的,并用作有机电致发光器件的组成部分。【在式中,Ar1和Ar2代表苯基或类似基团,R1和R2代表氢原子或类似基团,R3代表甲基或类似基团,m是0到2的整数,X代表2,4-吡啶基或类似基团,p是1或2,a和b为1或2,a+b为3,q为0或小于等于p的整数,M代表—MgR4基团或类似基团,R4代表氯原子或类似基团,r为p-q,Y代表离去基团。】
