    • Disclosed herein are am bipolar host compounds represented by formula (I), wherein: a) R 4 is an optionally substituted aryl or an optionally substituted heteroaryl group; b) n is at least 2; e) for each (ii) at least one of R 1 , R 2 and R 3 is independently an optionally substituted carbazole group, and the remaining of R 1 , R 2 and R 3 are independently selected from hydrogen, halogen and a C 1-20 organic group: and d ) Y is selected from (III), wherein R 5 is an.optionally substituted aryl group, an optionally substituted heteroaryl group, an optionally substituted alkyl group or an optionally substituted heteroalkyl group, and wherein R 6 is hydrogen,, an optionally substituted aryl group, an optionally substituted heteroaryl group, an optionally substituted alkyl -group or an optionally substituted heteroalky! group. The compounds can be used in OLED devices and are ambipolar. The OLED devices can show high efficiency and high luminance.
