The present disclosure generally relates to ionic compositions which may be used in or as an adhesive material for selectively adhering two items together. More particularly, but not exclusively, the present disclosure relates to ionic compositions that include a cationic imidazolium compound and an anionic compound such as a sulfonyl imide compound.

Ionic compositions and related uses thereof

An electrically debondable adhesive composition is described. The adhesive is comprised of a basic ionic liquid and an optionally crosslinked polymer, wherein the basic ionic liquid is comprised of an amino-ammonium cation and a bis(fluorosulfonyl)imide anion.

Basic ionic liquids compositions and elements including the same

Described herein are novel azo-benzene type chromophores. The chromophores are useful in photochromic compositions comprising a polymer matrix and a chromophore, wherein the chromophore is a novel azo-benzene type structure. The photochromic composition is photoresponsive upon irradiation by at least one wavelength of laser light across the visible light spectrum. Photochromic devices which comprise the novel azo-benzene type chromophore compound show significantly higher photoinduced birefringence, higher diffraction efficiency, and brighter images than devices that comprise well known azo-benzene chromophores. The photochromic composition may include a liquid crystal.

Chromophores for photochromic compositions useful for three dimensional display applications

This disclosure is related to photo-stable chromophores which are useful in various applications. Chromophores disclosed herein include a bis-triazole core, two electron-donors at C-4 and C-8, and two groups derived from pentaerythritol (R&#x2550;OR) or 1,1,1-tris(hydroxymethyl)methane (R&#x2550;H) at N-2 and N-6. Such structures have been proven to have greater then five times higher photo-stability than their analogs with simpler alkyl groups at N-2 and N-6.

Highly photo-stable bis-triazole fluorophores

This invention relates to an encapsulation structure comprising a luminescent wavelength conversion material for at least one solar cell or photovoltaic device which acts to enhance the solar harvesting efficiency of the solar cell device. The luminescent wavelength conversion material comprises at least one chromophore and an optically transparent polymer matrix. Application of the encapsulation structure, as disclosed herein, to solar harvesting devices, including solar cells, solar panels, and photovoltaic devices, improves the solar harvesting efficiency of the device by widening the spectrum of incoming sunlight that can be effectively converted into electricity by the device.

Wavelength conversion material as encapsulate for solar module systems to enhance solar harvesting efficiency

Described herein are wavelength conversion films that are easy-to-apply to solar cells, solar panels, or photovoltaic devices using an adhesive layer. The wavelength conversion films include a wavelength conversion layer with a photostable chromophore and are useful for improving the solar harvesting efficiency of solar cells, solar panels, and photovoltaic devices.

Wavelength conversion film having pressure sensitive adhesive layer to enhance solar harvesting efficiency

The invention provides highly fluorescent materials comprising a single (n=0) or a series (n=1, 2, etc.) of benzo heterocyclic systems. The photo-stable highly luminescent chromophores are useful in various applications, including in wavelength conversion films. Wavelength conversion films have the potential to significantly enhance the solar harvesting efficiency of photovoltaic or solar cell devices.
