摘要:
Tb(TMHD)3OPNP where TMHD is 2,2,6,6-tetramethyl-3,5-heptanedionato and OPNP is diphenylphosphonimide triphenyl phosphorane is an electroluminescent material which emits white light at an applied voltage of above 12 volts.
摘要:
According to the invention there is provided an electroluminescent device comprising in sequence, an anode a layer of an electroluminescent material of general formula L(α)aM where M is a rare earth, lanthanide or an actinide, Lα is a organic complex and n is the valence state of M and a cathode, in which the layer of an electroluminescent material includes a fluorescent dye.
摘要:
Material which is coated with a coating of an inherently conductive polymeric material. Suitable conductive polymeric materials include polypyrrole, substituted polypyrrole, polyaniline and substituted polyanilines.The coated powdery or granular metallic material may be used as an EMI and/or RFI shielding material.
摘要:
An electroluminescent device which has an electroluminescent layer formed of a binuclear, trinuclear or polynuclear rare earth organic complex in which the metals are linked through a bridging ligand.
摘要:
A method producing authenticatable documents by incorporating a fluorescent organometallic complex in the toner or in the paper in which the fluorescent organometallic complex gives off light with a characteristic spectrum when exposed to UV light.
摘要:
An inorganic powdery or granular material which is coated with a coating of an inherently conductive polymeric material, such as a conductive polypyrrole or substituted polypyrrole, a polythiophene or substituted polythiophene, a polyaniline or substituted polyaniline, a polyethylene oxide or an aniline copolymer. The material which is coated is talc, mica, wollastonite, calcium carbonate, aluminium hydroxide, clay or hydroxyapatite.
摘要:
In OLEDs, improved efficiency is obtained by novel compounds which can form inter alia electron injection layers of the formula (I) wherein R1 is a 1-5 ring aryl (including polycyclic), aralkyl or heteroaryl group which is optionally substituted with one or more C1-C4 alkyl, alkoxy or cyano; R2 and R3 together form a 1-5 ring aryl (including polycyclic), aralkyl or heteroaryl group which is optionally substituted with C1-C4 alkyl, alkoxy or cyano; R4 is hydrogen, C1-C4 alkyl or aryl; and Ar is monocyclic, bicyclic or tricyclic aryl or heteroaryl which is optionally substituted with one or more C1-C4-alkyl or alkoxy groups, or an oligomer thereof.
