合成了一种含N，N′-二苯基-N，N′-双（4-甲基苯基）-[1，1 ′-联苯]-4，4 ′-二胺（TPD）的新型丙烯酸酯作为电致发光器件的空穴传输层。用物理气相沉积法制备了该单体的薄膜。将所得薄膜用紫外光初步照射，然后在真空中加热至400 K。所得的聚合物膜（60 nm厚，其具有96%的聚合物转化率）具有光滑的表面。这种均匀的表面可以保持到420 K的加热。这些过程的沉积和聚合反应进行了监测与原位反射红外光谱。由聚合物薄膜制成的电致发光器件的效率比由单体薄膜制成的电致发光器件的效率高三倍。
A new acrylate bearing N,N′-diphenyl-N,N′-bis(4-methylphenyl)-[1,1′-biphenyl]-4,4′-diamine (TPD) was synthesized to apply for hole transport layer of an electroluminescent (EL) device. The thin film of this monomer was fabricated with physical vapor deposition. The obtained thin film was preliminarily irradiated with UV light and then heated up to 400K in vacuum. The resulting polymer film, 60nm thick, which had a polymer conversion of 96% had a smooth surface. This even surface could be maintained up to the heating of 420K. These processes of deposition and polymerization were monitored with in situ reflection infrared spectroscopy. The EL device made of polymer thin film had three times higher efficiency than that from the monomer thin film.
