Transition metal complex, polymer, mixture, formulation and use thereof
Disclosed are a transition metal complex, a polymer, a mixture, a composition and the use thereof, wherein the transition metal complex has a structure of the general formula as shown in formula (1):
The transition metal complex has a novel structure, and is an iridium (III) complex comprising rigid cycloalkyl groups. Since this type of auxiliary ligand increases the rigidity and symmetry of a molecule, the rigidity of a molecule is increased relative to a common ligand without the cycloalkyl groups, and as such, the whole complex has better chemical, optical, electrical and thermal stabilities. At the same time, since the modification occurs on the auxiliary ligand, the effect on the wavelength of the luminous maximum peak caused by a main ligand is relatively low, and therefore, a saturated luminous color may be retained. Therefore, the use of the transition metal complex according to the present invention in OLEDs, in particular as a doping material of a luminous layer, can provide a relatively high luminous efficiency and a relatively long lifetime of the device.
