The relationship between molecular shape of fluorescent blue dopants (BDs) and degree of molecular orientation was studied. BDs with larger ovality showed higher degree of orientation and higher external quantum efficiency (EQE) over 10% in a fluores

We developed highly efficient deep blue fluorescent materials. The bottom-emission OLED showed a CIE1931 coordinate of (0.14, 0.08) and a current efficiency of 6.5 cd/A with using a new efficiency-enhancement layer. We achieved CIEy of 0.062, a curre

The relevance of a new diphosphinite, which holds a natural bite angle around 120° in a catalyst complex, to the Rh(I)-catalyzed hydroformylation of certain olefins is examined, exhibiting a high turnover frequency (TOF) as compared with a typical 1

We developed a method to evaluate cell adherence to different intraocular lens (IOL) materials in one eye in which we coated one half of the anterior surface of a poly(methyl methacrylate) (PMMA) IOL with poly(dimethyl siloxane), a silicone material.

We found a new device structure which has an efficiency- enhancement layer between emitting layer and electron transporting layer. We applied the structure to a pure blue fluorescent device with a CIE1931 coordinate of (0.14, 0.12) and successfully o

We successfully synthesized a new excellent fluorescent deep blue dopant BD-4. The bottom emission device with BD-4 has a good color coordinate in CIE 1931 chromaticity of (0.140, 0.133) with high current efficiency of 6.46cd/A. BD-4 gives us better

We developed highly efficient fluorescent dopants for full-color OLEDs. For blue, green and red OLEDs, current efficiencies of 8.7cd/A, 20.5 cd/A and 11.4 cd/A at 10mA/cm2 were achieved, respectively. Lifetime of the blue device was estimated to be 2
