Design, Synthesis and Properties of D-π-A-π-D Type Organic Red Light Luminogens
To develop a novel red light luminescent material was important to prepare the high-efficiency organic light emitting devices. In this paper, a new kind of D--A--D red light luminogen utilizing fluorenone as acceptor and 3,4,5-trimethoxybenzene as donor was designed and synthesized, named 3MeFO. Its structure was confirmed by the,1,H NMR spectra,13,C NMR spectra and X-ray single crystal diffraction. The compound had strong charge transfer and -conjugated structure that contributed to the red shift and the PL peak of crystal was located at 620 nm. From the single crystal analysis, the introduction of methoxy groups had increased the intermolecular interaction owing to the formation of the hydrogen bond. Meanwhile, the compound exhibited excellent thermal stability properties, electrochemical performance that were benefit to prepare the OLED with the considerable electroluminescent properties.
