The present disclosure is drawn to methods and compositions directed at durable ink-jet inks. As such, an ink-jet ink can have a liquid vehicle, a colorant dispersed or dissolved in the liquid vehicle, a high Tg polymer having a Tg of at least 45.degree. C. dispersed in the liquid vehicle, and a near-infrared absorbing dye in the liquid vehicle. The ink can be formulated such that when printed on a substrate and irradiated with a near-infrared energy source, the near-infrared absorbing dye generates enough heat to uniformly melt the high Tg polymer, thereby enhancing the durability of ink-jet ink printed on the substrate.

The present disclosure relates to multichromophoric assemblies comprising metalloporphyrin scaffolds. The present disclosure also relates, in part, to methods for generating electric-field-stabilized geminate polaron pairs comprising applying electric fields to the multichromophoric assemblies described herein, or alternatively, directly to the metalloporphyrins provided by the present disclosure. The present disclosure further relates, in part, to multichromophoric assemblies comprising metalloporphyrin scaffolds, which exhibit enhanced energy transfer properties.
摘要:
The present invention provides a light-absorbing material capable of providing high photoelectric conversion efficiency when applied to a photoelectric conversion element. The light-absorbing material of the present invention has a structure represented by Formula (1) below:
X-Y (1)
(wherein X represents a light-absorbing site, and Y represents a radical site that becomes a radical when in an oxidized state and/or when in a reduced state, and is capable of repeated oxidation-reduction).
摘要:
The invention discloses compounds and compositions for dual phototherapy and combined therapy and diagnosis of tumors and other lesions. The compounds have a Dye that, when photoactivated, operates via Type I and/or Type II mechanisms. Other Dye or azide components may operate by the same or different mechanisms. Selection of particular components in a compound, and formulation of the compound(s) in a composition permit different activation wavelengths to be used for different therapies. A targeting moiety may be added to the compound or composition so that the Dye locates at a particular site, such as a hormone-sensitive tumor, for diagnosis and/or treatment. The compounds and compositions may be incorporated within liposomes.
摘要:
A material comprising at least one polymer and at least one sensitizer wherein the sensitizer is localised at a surface of the material wherein the sensitizer is an agent or compound able to provide improved anti-bacterial and/or anti-viral activity following exposure of the sensitizer to a particular wavelength or range of wavelengths of electromagnetic radiation.

Disclosed herein is a method for preparing oxytitanium phthalocyanine as a charge generating material. The method comprises the steps of mixing 30~100wt% sulfuric acid and an oxytitanium phthalocyanine crude in a mixing ratio between 100:1 and 1:1, homogeneously grinding the mixture in a wet grinder filled with zirconia or glass beads as grinding media at -20°C~60°C for 0.1~24 hours, and removing the grinding media from the ground mixture using a solvent. According to the method, oxytitanium phthalocyanine usable as a high-quality charge generating material can be prepared without the use of expensive and difficult-to-handle reactants, such as trifluoroacetic acid and pentafluoropropionic acid. Further disclosed is an oxytitanium phthalocyanine charge generating material prepared by the method.
