Aggregation-Induced Emission: Together We Shine, United We Soar!

Poly(N-isopropylacrylamide): experiment, theory and application

Flexible graphene films were prepared by the filtration of water-soluble noncovalently functionalized graphene sheets with pyrenebutyrate. The work presented here will not only open a new way for preparing water-soluble graphene dispersions but also provide a general route for fabricating conducting films based on graphene.

Thermo- and pH-responsive polymers in drug delivery.

Photophysics of preassociated pyrenes in aqueous polymer solutions and in other organized media

Phase transition of aqueous poly-(N-isopropylacrylamide) solutions: a study by non-radiative energy transfer

Disclosed is an ink composition consisting essentially of water, diethylene glycol-monobutyl ether, glycerol, an optional cyclohexyl pyrrolidinone component, a dye selected from the group consisting of dyes containing dansyl chromophores and dyes containing porphyrin chromophores, an optional biocide, and an optional polyalkylene oxide/bisphenol-A additive.

Colorless fast-drying ink compositions for printing concealed images detectable by fluorescence

An ink jet ink composition which comprises water, a solvent, and a plurality of colored particles comprising hydrophilic porous silica particles, to the surfaces of which dyes are covalently bonded through silane coupling agents. The particles are prepared by a process which copmrises reacting hydrophilic porous silica particles with a silane coupling agent in the absence of water to form particles having covalently attached thereto coupling agents, followed by reacting a dye with the coupling agent attached to the silica particles.

Ink jet inks containing colored silica particles

Disclosed is an ink composition which comprises an aqeuous liquid vehicle and particles of an average diameter of 100 nanometers or less which comprise micelles of block copolymers of the formula ABA, wherein A represents a hydrophilic segment and B represents a hydrophobic segment, and wherein dye molecules are covalently attached to the micelles, said dye molecules being detectable when exposed to radiation outside the visible wavelength range. Optionally, silica is precipitated within the micelles. In a specific embodiment, the dye molecules are substantially colorless. In another specific embodiment, the ink also contains a colorant detectable in the visible wavelength range.
