Green-light iridium (III) coordination compounds containing oxadiazole base groups as well as preparation method and application thereof

The invention relates to the coordination compounds of iridium containing an oxadiazole base groups, which have the following structural formula, the iridium coordination compounds disclosed in the invention can be used for a luminous layer in an electroluminescent device. On the basis of ternary phenylpyridine iridium, 16 green-light coordination compounds with better property are aggregately obtained by introducing different base groups at each position on oxazole phenyl. The invention discloses a preparation method of the coordination compounds of the iridium containing the oxadiazole base groups.
