SPIRO COMPOUND HAVING EXCELLENT THERMAL STABILITY, MEMBRANE STABILITY, AND QUANTUM EFFICIENCY, AND AN ORGANIC ELECTROLUMINESCENT DEVICE HAVING EXCELLENT EFFICIENCY, LONG LIFETIME, AND HIGH STABILITY
SPIRO COMPOUND HAVING EXCELLENT THERMAL STABILITY, MEMBRANE STABILITY, AND QUANTUM EFFICIENCY, AND AN ORGANIC ELECTROLUMINESCENT DEVICE HAVING EXCELLENT EFFICIENCY, LONG LIFETIME, AND HIGH STABILITY
PURPOSE: A spiro compound is provided to have excellent quantum efficiency together with excellent thermal stability and membrane stability, in case of using for a hole transport material of an organic electroluminescent device, a dopant material of a light-emitting layer, a host material of a light-emitting layer, an electron transport material, a host of fluorescent material, a fluorescent device and a phosphorescent device.;CONSTITUTION: A spiro compound is in chemical formula 1. In chemical formula 1, R^1-R^6 are same or different, and can't be hydrogen altogether, at least one of R^1-R^6 is one of functional groups in chemical formula 1-a, 1-b, 1-c, and a-d, and residue of R^1-R^6 is respectively a C1-9 alkyl group, a C6-30 aryl group, or a C5-30 heteroaryl, or at least one of R^1-R^6 is able to form a carbon-conjugated aromatic cycle or a heteroaromatic cycle by combining with carbon in adjacent benzene ring. R^7-R^9 is respectively hydrogen or a C1-9 alkyl group.;COPYRIGHT KIPO 2012
