Abstract
A structured organic film with an added functionality comprising a plurality of segments and a plurality of linkers arranged as a covalent organic framework, wherein the structured organic film may be a multi-segment thick structured organic film.
Claims28
A structured organic film (SOF) comprising a plurality of segments including at least a first segment type a plurality of linker including at least a first linker type arranged as a covalent organic framework (COF), wherein the first segment type and/or the first linker type comprises at least one atom that is not carbon and the SOF has an added functionality;
- wherein the SOF has a thermal stability higher than 400° C. under atmospheric conditions;
- and wherein the SOF is a substantially defect-free film that contains less than 10 pinholes, pores or gaps greater than about 250 nanometers in diameter per cm2.
A process for preparing a structured organic film (SOF) with an added functionality comprising:
- (a)preparing a liquid-containing reaction mixture comprising:
- a plurality of molecular building blocks each comprising a segment and a number of functional groups, wherein the molecular building blocks possess an inclined property;
- (b)depositing the reaction mixture as a wet film;
- and
- (c)promoting change of the wet film to form a day SOF with an added functionality;
- wherein the dry SOF has a thermal stability higher than 400° C. under atmospheric conditions;
- and wherein the SOF is a substantially defect-free film that contains less than 10 pinholes, pores or gaps greater than about 250 nanometers in diameter per cm2.
A structured organic film (SOF) comprising a plurality of segments including at a frist segment type and a plurality of linkers including at least a first linker type arranged as a covalent organic framework (COF), wherein
- the first segment type and/or the first linker type comprises a hydrogen, and the SOF has an added functionality, and
- the dry SOF has a thermal stability higher than 400° C. under atmospheric conditions, wherein the SOF is a substantially defect-free film that contains less than 10 pinholes, pores or gaps greater than about 250 nanometers in diameter per cm2.
