Abstract
A method of forming a pre-cure solution for a structured organic film (SOF) is described, including contacting at least one type of segment and at least one type of pre-linker with a bio-based solvent. The method also includes dissolving the at least one type of segment and the at least one type of pre-linker within the bio-based solvent. The method also includes where the bio-based solvent has a viscosity above 0.92 MPa-s. A composition including a bio-based solvent is also disclosed.

A method of forming a pre-cure solution for a structured organic film (SOF), comprising:
- contacting at least one segment and at least one pre-linker comprising a polyol, a diamine, a polyamine, or a combination thereof, with a bio-based solvent;
- and
- dissolving the at least one segment and the at least one pre-linker within the bio-based solvent;
- and
- wherein the bio-based solvent comprises 1-butylpyrrolidin-2-one, methyl-5-(dimethylamino)-2-methyl-5-oxopentanoate, dimethyl isosorbide, glycofurol, triacetin, diethylene glycol monoethyl ether acetate, acetyltributylcitrate, acetyltriethylcitrate, triethyl citrate, or combinations thereof.
A method of forming a pre-cure solution for a structured organic film (SOF), comprising:
- contacting at least one segment and at least one pre-linker comprising a polyol, a diamine, a polyamine, or a combination thereof, with a bio-based solvent;
- heating the at least one segment and the at least one pre-linker with the bio-based solvent;
- and
- dissolving the at least one segment and the at least one pre-linker within the bio-based solvent;
- forming a structured organic film (SOF) on a substrate from the pre-cure solution;
- and
- curing the structured organic film (SOF), wherein:
- the bio-based solvent comprises 1-butylpyrrolidin-2-one, methyl-5-(dimethylamino)-2-methyl-5-oxopentanoate, dimethyl isosorbide, glycofurol, triacetin, diethylene glycol monoethyl ether acetate, acetyltributylcitrate, acetyltriethylcitrate, triethyl citrate, or combinations thereof;
- and
- heating the at least one segment and the at least one pre-linker and the bio-based solvent is performed before or after dissolving the at least one segment and the at least one pre-linker within the bio-based solvent.
A composition, comprising:
- a bio-based solvent;
- at least one structured organic film (SOF) segment;
- and
- at least one structured organic film (SOF) pre-linker comprising a polyol, a diamine, a polyamine, or a combination thereof;
- and
- wherein the bio-based solvent comprises 1-butylpyrrolidin-2-one, methyl-5-(dimethylamino)-2-methyl-5-oxopentanoate, dimethyl isosorbide, glycofurol, triacetin, diethylene glycol monoethyl ether acetate, acetyltributylcitrate, acetyltriethylcitrate, triethyl citrate, or combinations thereof.
