    Abstract: Described herein are embodiments of squarylium compounds for use as filters in light-emitting and/or display devices. One problem of known quarylium dyes is that strong nucleophiles can attack the electron-deficient cyclobutene ring which can lead to a loss of the dye's colour. Another potential drawback with squaraine dyes can be their tendency to form aggregates, which can lead to a substantial broadening of their absorption bands. Use of the present compounds in filters address these problems. The squarylium compounds of the present invention have the following formulas:

    Abstract: Described herein is a graphene oxide and polymer based selectively permeable element that provides selective gas, and vapor resistance for dehumidification applications. The graphene oxide is cross-linked with polyvinyl alcohol, the polymer comprises an ammonium salt polymer such as poly(diallyldimethylammonium) chloride. Also described is a selectively permeable element where the graphene may be selected from reduced graphene oxide, graphene oxide, and is also functionalized or crosslinked. Also described is a selectively permeable element where there is crosslinking between the graphene and/or the polymers to provide enhanced gas resistance with water vapor permeability. A selectively permeable device is also described that incorporates the selectively permeable element and further comprises a substrate and a protective coating, encompassing the selectively permeable element. Also described are methods for making the aforementioned selectively permeable elements and related devices.
