The present disclosure discloses a charging socket having a light guide device, including: a charging socket housing including a charging socket front housing, an upper surface of the charging socket front housing being provided with a transparent panel; a light source provided in the charging socket housing; and the light guide device provided in the charging socket housing, the light guide device being attached to or close to the light source, attached to or close to the transparent panel, and guiding light of the light source to the transparent panel. The charging socket can improve the user experience and delight customers.

Charging socket having light guide device

The present invention relates to novel compounds that are useful as ligands in organometallic dyes. More particularly, the invention relates to dyes comprising the compounds, said dyes being sensitizing dyes useful in solar cell technology. According to an embodiment, the present invention discloses new ruthenium dyes and their application in dye-sensitized solar cells (DSC). The referred ruthenium dyes with new structural features can be easily synthesized, show more than 85% light-to-electricity conversion efficiency and a higher than 9% cell efficiency.

High molecular extinction coefficient metal dyes

The present invention refers to using the principal of a room temperature molten ionic liquid, to an electrolyte, to devices comprising the ionic liquid co-melting, and to the preparation of a room temperature ionic liquid via various physical and chemical methods. The room temperature molten ionic liquid comprises at least two component salts, at least one of which is not molten at room temperature, but, if combined with another salt, is in the molten state at room temperature.

Eutectic melts

Biphenyl tetracarboxlic acid esters and derivatives thereof are prepared by the coupling reaction of 4-halogen substituted o-benzenedicarboxylic acid ester, carried out in an aprotic polar solvent in the presence of a pre-prepared triphenylphosphine-nickel chloride or trialkylphosphine-nickel chloride catalyst, zinc powder as the reducing agent, and an alkali metal halide promoting agent. The ester may be hydrolyzed in basic solution to afford the corresponding acid. The acid may be heated or boiled with acetic anhydride to afford the biphenyl dianhydride.
