Described herein are polymeric compounds including an acceptor dye and donor luminophore, a polymer, and optionally a bioconjugate group. A polymeric compound of the present invention may have a structure represented by: A-B-C or C-A-B, wherein A is an acceptor dye; B is a polymer comprising one or more hydrophobic unit(s) and one or more hydrophilic unit(s); and optionally C, wherein C, when present, comprises a bioconjugate group, wherein one or more donor luminophore(s) are each separately attached to a portion of the polymer and/or to a portion of the acceptor dye. Also described herein are compositions comprising the polymeric compounds and methods of preparing and using the same.

A series of novel molecular conjugates is disclosed herein, consisting of a photosensitizer moiety chemically bonded to at least one diazirine moiety. Such conjugates react in air and/or water with non-coherent visible light to form singlet oxygen, an energetic species known to be highly toxic to abroad range of pathogens, including bacteria, fungi, microbial biofilms and viruses. Such non-specific cellular damage limits the pathogen's ability to evolve into a resistant form. The diazirine moiety of the conjugate enables the reagent to be adhesively bonded to a plethora of substrates, such as, for example, polymers, non-woven fabrics, surgical masks and gloves, hospital gowns, hospital surfaces (such as counters, mattresses, curtains) medical implants, bandages, wound dressings, or air-filters. The resulting treated substrates act as an effective pathogen-killing barrier, providing protection against the spread of such pathogens to non-infected persons.

The present application discloses a color resist material, a filter, and a preparation method thereof. The color resist material is a trimer structure formed by polymerizing phthalocyanine dyes, wherein groups with double bonds are introduced on the phthalocyanine dyes to construct a three-molecule complex by a complexing agent, and the phthalocyanine dyes are connected by the double bonds to form a trimer structure. The color resist material with the trimer structure is stably stored in a photoresist liquid and has excellent solvent resistance, while maintains good solubility. Accordingly, a filter made of the color resist material has high transmittance and good optical performance.
