2-(甲基)-6-叔丁基-4H-吡喃酮的新的合成方法及BDCM系列红光染料的合成及其在OLED中的应用

In the interest of driving down the cost of DCM-type light emitting materials, we have found a new approach to prepare 2-（t-butyl）-6-methy1-4H-pyrone, which is cost effective and more amenable to large scale production than the reported method. Furthermore, three new DCM-type dyes, N,N-bis-[p-（2-（4-dicyanomethylene-6-t-butyl-4H- pyran-2-yl）-vinyl）-phenyl]-4-t-butyl-aniline （BDCM-BA）, N,N-bis-[p-（2-（4-dicyanomethylene-6-t-butyl-4H-pyran- 2-yl）-vinyl）-phenyl]aniline （BDCM-A） and N,N-bis-[p-（2-（4-dicyanomethylene-6-t-butyl-4H-pyran-2-yl）-vinyl）- phenyl]-4-methoxyl-aniline （BDCM-MA） were synthesized in good yields using 2-（t-butyl）-6-methyl-4H-pyrone as starting material. They can be utilized in OLEDs as nondoped red emitting materials as the result of the restricted concentration quenching effect.
