Abstract
A porous structured organic film for storing gaseous a gaseous entity and method for storing gaseous entities in a porous structured organic film, the porous structured organic film including a plurality of segments and a plurality of linkers arranged as a covalent organic framework, wherein at a macroscopic level the covalent organic framework is a film and contains a plurality of sites accessible to one or more gaseous entity.
Claims19
A method for storing a gaseous entity, the method comprising:
- contacting the gaseous entity with a sorbent material, the sorbent material comprising a porous structured organic film (SOF) comprising a plurality of segments including at least a first segment type and a plurality of linkers including at least a first linker type arranged as a covalent organic framework (COF), and a plurality of pores, wherein
- the first segment type and/or the first linker type comprises at least one atom that is not carbon, and
- the plurality of pores comprises a plurality of accessible sites for uptake and storage of the gaseous entity;
- and
- storing the gaseous entity for a predetermined duration.

A method for storing a gaseous entity, the method comprising:
- contacting the gaseous entity with a sorbent material, the sorbent material comprising a porous structured organic film (SOF) comprising a plurality of segments including at least a first segment type and a plurality of linkers including at least a first linker type arranged as a covalent organic framework (COF), and a plurality of pores, wherein
- the gaseous chemical entity is present in the SOF at a concentration from about 1.1 times greater than the natural compressibility of the gaseous chemical entity to about the concentration of the gaseous chemical entity upon its liquification,
- the first segment type and/or the first linker type comprises at least one atom that is not carbon, and
- the plurality of pores comprises a plurality of accessible sites for uptake and storage of the gaseous entity;
- and
- storing the gaseous entity for a predetermined duration.
