New hole injection layer (HIL) materials for organic light-emitting diodes (OLEDs) based on phenothiazine and phenoxazine were synthesized, and the electro-optical properties of the synthesized materials were examined by UV-vis and photoluminescence spectroscopy, and by cyclic voltammetry. 10,10'-bis(4-tert-butylphenyl)-N7,N7'-di(naphthalen-1-yl)-N7,N7'-diphenyl-10H,10'H-3,30-biphenoxazine-7,7'-diamine (1-PNA-BPBPOX) showed glass transition temperatures (Tg) of 161 oC, which was higher than that (110oC) of Tris(N-(naphthalen-2-yl)-N-phenyl-amino) triphenylamine (2-TNATA), a commercial HIL material. |
