Paragraph 0047; 0048; 0049, (2017/09/12)
The invention provides an arylamino-containing fluorene type derivative. The arylamino-containing fluorene type derivative has the structure as shown in a formula (1), wherein Ar is selected from fluorenylidene or indenylidenofluorenyl; R1 and R2 are independently selected from one of H, C1-12 aliphatic alkyl, C1-12 aliphatic cycloalkyl, C6-30 aryl, C6-30 heterocyclic aryl and triarylamine; Ar1 and Ar2 are respectively and independently selected from C1-12 aliphatic alkyl, C1-12 aliphatic cycloalkyl or C6-30 aryl; L1 and L2 are respectively and independently selected from a single bond, C1-20 alkylene, substituted or unsubstituted C6-30 arylene and subsituted or unsubstituted C6-30 heteroarylene; and the premise is that R1 and R2 are not H at the same time. The compound has stable nature, the preparation process is simple, and when the compound is used as a phosphorescent host material in an electroluminescent device, the device shows relatively high luminous efficiency and relatively low turn-on voltage. The formula is as described in the specification.
