The invention provides a ruthenium (II)-polypyridine complex. For the ruthenium (II)-polypyridine complex, bipyridyl (bpy) or phenanthroline hydrate (phen) is used as an ancillary ligand, and dipyridine[3,2-a:2',3'-c]phenazine-11,12-imidazole (dppzi) is used as a main ligand. The preparation method comprises the following steps: preparing 5,6-dinitrobenzimidazole from 5,6-nitrobenzimidazole; reducing 5,6-dinitrobenzimidazole into 5,6-diaminobenzimidazole by using hydrazine hydrate and palladium/carbon; preparing dppzi from phenanthroline hydrate-5,6-dione and 5,6-diaminobenzimidazole and preparing cis-[Ru(bpy)2Cl2].2H2O from ruthenium trichloride, bpy and lithium chloride; preparing cis-[Ru(phen)2Cl2].3H2O from ruthenium trichloride, phen and lithium chloride; carrying out a heating reflux reaction on dppzi and cis-[Ru(bpy)2Cl2].2H2O or cis-[Ru(phen)2Cl2].3H2O under the protection of argon, carrying out cooling, adding ammonium hexafluorophosphate, allowing precipitate to deposit and carrying out filtration and column chromatography so as to obtain a target product. The ruthenium (II)-polypyridine complex provided in the invention can be used as an optical switch for G-quadruplex DNA molecules.

The present invention provides a fluorescent dye-silane hybrid resin manufactured by polycondensing an alkoxysilane bonded with a fluorescent dye with an organo-silane. More particularly, the present invention provides a fluorescent dye-siloxane hybrid resin that is manufactured by reacting a fluorescent dye having one or more functional groups with an alkoxysilane having an organic functional group to form an alkoxysilane bonded with the fluorescent dye and then polycondensing the alkoxysilane bonded with a fluorescent dye with an organo-silanediol and an organo-alkoxysilane having a thermocurable or ultraviolet-curable functional group without water. The fluorescent dye-silane hybrid resin has excellent thermostability, photostability, fluorescence characteristics, and processibility.

Provided is a novel electrochemical display element which performs bright white display, high contrast black/white display and full-color display with a simple member configuration. A method for driving such display element is also provided. The display element contains an electrochromic compound, which is colored or has its color disappear due to oxidation or reduction, a metallic salt compound, an electrolyte and a white scattered material, between opposing electrodes. The display element substantially performs multiple color display of three colors or more, i.e., black display, white display and colored display other than black, by driving operation of the opposing electrodes.
