Thienyl-dibenzoazepines and their derivatives as donor for xanthene-based short-wave infrared (SWIR) dyes
Description:
Overview of Technology
Novel xanthene-based NIR-II dyes that are simple to make, can be readily modified, and exhibit remarkable photophysical properties to allow for photo acoustical imaging, high molar absorptivity, low quantum yields, and SWIR absorbance.
Background
NIR- II dyes are highly sought for deep tissue imaging of biomolecules. Alternatively, they can be used in other applications such as lasers, night vision cameras, infrared sensors, light detection and ranging in automotive industry, laser protection eye wares, light filters, welding protectors, eye tracking, screen technology and measuring technology.
Technology Description
This invention describes novel xanthene-based NIR- II dye structures containing strong anti aromatic and non-aromatic donors. These dyes have good molar absorptivity and emission when compared to dyes in this wavelength range and can be tuned to for photo acoustic or fluorescence imaging. They can also be functionalized, like all xanthene-based dyes, for sensing applications.
Benefits
- Multiple applications
- Good molar absorptivity and emission
- Can be functionalized for screening applications
Applications
These dyes are highly sought for applications in biological imaging, lasers, night vision cameras, infrared sensors, light detection and ranging in automotive industry, laser protection eye wares, light filters, welding protectors, eye tracking, screen technology and measuring technology. Can also be used for other applications aside from imaging, such as vision cameras and sensors, light detection, measurement and screen technologies etc.
