Abstract: The invention discloses novel sulfur-containing naphthalimide derivatives, and the preparation and uses thereof. The conjugated plane of naphthalimide derivatives of the invention is enlarged by incorporating 5-or 6-membered heteroaromatic ring and/or introducing S heteroatom, thus increasing the anti-tumor activity of naphthalimide. The compounds of the invention displays significant inhibiting activities to the proliferation of various tumor cells such as human lung cancer, gastric cancer, liver cancer, leucocythemia and the like. The inhibition of cell proliferation is dose-dependent.

Abstract: The invention provides a kind of polymer grafted long afterglow phosphor which composed of alkali earth aluminate phosphor grafted by polymer through coordination bond and a method for producing the same. The method for producing a polymer grafted phosphor comprise two steps: the alkali earth aluminate activated by rare earth ions is coordinated with difunctional ligand to form a coordinated long afterglow phosphor; The coordinated long afterglow phosphor was dispersed in organic solvent at 40˜130° C., the ligand was initiated by initiator and could copolymerize with other polymerizable monomer to form the polymer grafted long afterglow phosphor. The formed phosphors have good water resistance and luminescent properties. They can be widely used in fields of luminescent coatings, paints and plastics.

Abstract: Protein macromolecular dyes, A(B)b are disclosed, wherein A are protein macromolecules including natural protein macromolecules and modified natural protein macromolecules such as casein, gelatin and fur-protein; B are dyes including azo dyes, azo metal complex dyes and anthraquinone dyes which can react with the amino groups of the natural and modified protein macromolecules; b are integers between 1˜2500. The protein macromolecular dyes have excellent properties of crosslinking ability, better dyeing fastness, fixation ration than conventional dyes and the function of normal macromolecules such as compatibility, abilities of filling and forming membranes. They may be used in dyeing protein materials such as leather, wool and silk.
