Abstract
Processes for preparing structured organic films (SOFs) comprising a plurality of segments and a plurality of linkers arranged as a covalent organic framework. The processes for preparing structured organic film may include mixing a plurality of molecular building blocks each comprising a segment and a number of functional groups to form a mixture of molecular building blocks; heating the mixture to form a homogeneous liquid comprising pre-SOFs; depositing the homogeneous liquid comprising pre-SOFs as a wet layer; and drying the wet layer to form a dry SOF from the pre-SOFs.

A process for preparing a structured organic film (SOF) comprising:
- (a) mixing a plurality of molecular building blocks each comprising a segment and a number of functional groups to form a mixture of molecular building blocks;
- (b) heating the mixture to form a homogeneous liquid comprising a pre-SOF;
- (c) depositing the homogeneous liquid comprising the pre-SOF as a wet layer;
- and
- (d) drying the wet layer to form a dry SOF from the pre-SOF.
A process for preparing a structured organic film (SOF) comprising:
- (a) mixing a plurality of molecular building blocks each comprising a segment and a number of functional groups with a solvent to form a mixture of molecular building blocks, wherein the concentration of molecular building blocks in the mixture is from about 80 wt % to about 95 wt %,
- (b) heating the mixture to form a homogeneous liquid comprising pre-SOFs;
- (c) depositing the homogeneous liquid comprising pre-SOFs as a wet layer;
- and
- (d) drying the wet layer to form a dry SOF from the pre-SOFs.
A process for preparing a structured organic film (SOF) comprising:
- (a) mixing a plurality of molecular building blocks each comprising a segment and a number of functional groups with a solvent to form a mixture of molecular building blocks, wherein the concentration of molecular building blocks in the mixture is from about 80 wt % to about 95 wt %;
- (b) heating the mixture to form a homogeneous liquid comprising pre-SOFs;
- (c) diluting the homogeneous liquid comprising the pre-SOFs with a solvent to form a diluted homogeneous liquid comprising pre-SOFs, wherein the concentration of molecular building blocks in the diluted homogeneous liquid is from about 5 wt % to about 75 wt %;
- (d) coating the diluted homogeneous liquid comprising the pre-SOFs on a substrate to form a wet layer;
- and
- (e) drying the wet layer to form a dry SOF from the pre-SOFs.
