Abstract
A chemical structure, and a process for synthesizing the chemical structure, of:
Claims20
A chemical structure of:
A process comprising:
- synthesizing a polymer with intrinsic microscopy (PIM-1) by polycondensation reaction of one-dimensional monomers, the PIM-1 comprising a nitrile (—CN) group, the one-dimensional monomers comprising:
- 3,3,3′3′-tetramethyl-1,1′-spirobisindane-5,5′,6,6′-tetrol (TTSBI);
- and
- 1,3-dicyanotetrafluorobenzene (DCTB);
- functionalizing the PIM-1 with a carboxylic acid (—COOH) group by converting the —CN to the —COOH, the functionalizing of the PIM-1 resulting in a hydrolyzed polymer (PIM-1-Cn), a degree of functionalization of the PIM-1 being controlled, in part, by:
- adjusting a reaction temperature;
- and
- adjusting a reaction time;
- and
- reacting the PIM-1-Cn through an acid-base interaction, the PIM-1-Cn being reacted with tris(2-aminoehtyl)amine (TAEA), the reacted PIM-1-Cn resulting in a primary amine-appended sorbent (PIM-1-Cn-TA).
