Abstract
The present disclosure relates to a composition that includes a sequestering material capable of binding a target material, where the sequestering material includes a first component that includes at least one of a functional group, a molecule, an oligomer, or a polymer, and the target material includes at least one of an element, a chemical, and/or a compound. In some embodiments of the present disclosure, the element may include at least one element from at least one of Rows 4, 5, 6, and 7 of the Periodic Table and/or an inner transition metal.
Claims18
A method comprising:
- mixing a first component and a matrix material to form a sequestering material;
- and
- applying a layer of the sequestering material to an electronic device comprising a perovskite layer comprising at least one of lead, tin, or bismuth, or a combination thereof, wherein:
- the first component comprises at least one of a phosphonic group, a phosphate group, a phosphono group, a phosphor group, a phosphoryl group, a hydroxyl group, or a carboxylic acid group, or a combination thereof,
- the matrix material comprises at least one of a polymer, an oligomer, an oxide, a glass, a silicone gel, or a combination thereof, and
- the sequestering material is capable of binding at least one of lead, tin, or bismuth, or a combination thereof.
