79 results about "Triphenylethylene" patented technology

Triphenylethylene (TPE) is a simple aromatic hydrocarbon that possesses weak estrogenic activity. Its estrogenic effects were discovered in 1937. TPE was derived from structural modification of the more potent estrogen diethylstilbestrol, which is a member of the stilbestrol group of nonsteroidal estrogens.

Tetraphenylethylene blue-fluorescence organic compound, preparation method thereof and blue organic electroluminescence device

The invention provides a tetraphenylethylene blue-fluorescence organic compound and a preparation method for an organic electroluminescence device thereof. A structure of the tetraphenylethylene blue-fluorescence organic compound is as shown in formula (I): wherein Ar is a naphthyl. The compound is capable of enabling the naphthyl and a triphenylethylene group to be connected with anthracene, using the anthracene as a fundamental luminescence group, and using triphenylethylene and naphthalene as modification for transforming a structure or a group of the anthracene, wherein the triphenylethylene and the anthracene form a structure similar to tetraphenyl ethylene. Because the tetraphenyl ethylene structure can produce an aggregation-induced emission (AIE) effect, a phenomenon of exciton annihilation can be effectively inhibited, so a molecule has the stronger fluorescence emission in a high-concentration aggregation state than that in a low-concentration. In addition, because a relativemolecular weight of the compound is larger, an aromatic structure and an ethylene structure have a conjugate condition, the finally prepared compound is good in heat stability, and has the high luminance brightness, and the prepared device is good in performance.
