Номер: US7928278B2

The subject invention pertains to a method, apparatus, and composition of matter for producing near-infrared (near-IR) radiation. The subject invention can incorporate a polymer and a metal-containing compound, wherein the metal-containing compound can incorporate a metal-ligand complex, wherein when the metal-ligand complex becomes excited, energy is transferred from the ligand to the metal, wherein, the energy transferred to the metal by sensitization is emitted as near-infrared radiation. In a specific embodiment, the subject invention relates to a composition of matter having a luminescent polymer and a metal containing compound where the metal containing compound incorporates a metal-ligand complex such that the absorption spectrum of the metal-ligand complex at least partially overlaps with the emission spectrum of the luminescent polymer. As the absorption spectrum of the metal-ligand complex at least partially overlaps with the emission spectrum of the luminescent polymer, when the luminescent polymer becomes electronically excited energy can be transferred from the luminescent polymer to the metal-ligand complex. At least a portion of the energy transferred from the luminescent polymer to the metal-ligand complex can then be emitted by the metal-ligand complex as near-infrared radiation. The subject invention can incorporate polymers which are conjugated or non-conjugated and luminescent or non-luminescent. In a specific embodiment, conjugated polymers which are luminescent can be utilized.

Essentially thickness independent single layer photoelastic coating

Номер: WO2006091927A1

An essentially thickness independent luminescent photoelastic coating consists of a single layer of a photoelastic material in which a polarizing preserving luminescent dye, (1), and an excitation absorption dye, (2), are contained therein. The absorption dye limits a penetration depth, (3), of incident radiation, (4). The thickness of the coating is greater than a penetration depth of the excitation radiation. The coating is used to determine strain on an underlying substrate, (5), on which the coating is adhered by measurement and analysis of the emission intensities and patterns from the luminescent dye in the coating upon irradiation at a distinct excitation radiation.

Thiophene based oligomers as light activated biocides

Номер: WO2013055417A3

Thiophene containing water-soluble oligomers were synthesized and characterized. The photophysical properties of these compounds were studied; transient absorption spectroscopy was used to probe the triplet excited state and their ability to sensitize singlet oxygen was spectroscopically monitored in deuterated methanol. The above compounds were tested for their light activated biocidal properties against S. aureus both under UV and visible radiation. Among the oligomers studied, the terthiophene derivative was found to kill the bacteria efficiently.
