A soluble 5-carbazolium-8-hydroxyquinoline Al(III) complex as a dipolar luminescent material

A novel 8-hydroxyquinoline derivative with a carbazole group substituting in the 5-position of quinoline was synthesized, where carbazole acted as a hole transporter. The single crystal of this 8-hydroxyquinoline derivative was obtained. Its coordination complex with Al(III) was also synthesized. This complex with the ability of hole transportation and electron transportation simultaneously was soluble in common organic solvents and showed yellow luminescence with high quantum yield.
