  • Patent number: 10050214
    Abstract: The present invention relates to a near-ultraviolet stimulated light-emitting compound, and more specifically relates to a fluorescent quinazolinone compound which is stimulated in the near ultraviolet region. The fluorescent quinazolinone compound according to the present invention is colorless in daylight but exhibits a high fluorescent intensity when irradiated with light in the near ultraviolet region. Also, the fluorescent quinazolinone compound can be easily used with printed and plastic molded products since the compound not only has a high degree of light fastness and thermal stability but also high dispersibility.

  • Patent number: 7897735
    Abstract: Provided are an electron donor-azo-electron acceptor compound having a thiol-based anchoring group, a method of synthesizing the compound, and a molecular electronic device having a molecular active layer formed of the compound. The compound for forming a molecular electronic device includes an azo compound that has a dinitrothiophene group and an aminobenzene group having thiol derivatives. The compound forms a molecular active layer in the molecular electronic devices. The molecular active layer is self-assembled on an electrode using the thiol derivative in the azo compound as an anchoring group. The molecular active layer in the molecular electronic device forms a switching device switching between an on-state and an off-state in response to a voltage applied to electrodes or a memory device storing a predetermined electric signal in response to a voltage applied to the electrodes.

  • Patent number: 7637119
    Abstract: In the related art refrigerator, its structure for supplying water to a dispenser and water tank was complicated. In addition, since an icemaker is installed in a refrigerating chamber of the refrigerator, there is a problem in that the water supplied into the icemaker is frozen. Furthermore, if the icemaker is installed in the freezing chamber of the refrigerator in which the refrigerating chamber is formed at a lower portion thereof and a refrigerating chamber is formed at an upper portion thereof, there is another problem in that it is difficult to control the temperature in the refrigerating chamber or ice-making capability of the icemaker is lowered. The present invention is directed to a refrigerator.
