    • Of course, the dehydrocondensing reaction can be performed efficiently in commonly used neutral aprotic organic solvents (Ref. 10).

    • note
    • For polymer dehydrocondensing reagents, catalytic decarbonylation of highly toxic diisocyanatohexane was reported to give hexamethylenecarbodiimide as a linear polymeric structure (Ref. 19a). More recently, a high-loading polymer-gel carrying fluoroformamidinium salt was prepared by ring opening metathesis polymerization (ROMP) (Ref. 19b).

    • Both the degree of polymerization and cross-linking are unclear because Poly-O-Trz-Cl is insoluble in any common solvents.

    • CDMT cannot react directly with carboxylic acid whereas DMT-MM can react with carboxylic acid leading to the formation of amides or esters (Ref. 24). Therefore, the addition of NMM to Poly-Trz-Cl to generate Poly-Trz-MM is essential for dehydrocondensation.

    • With regard to the cross-linking Poly-N-Trz-Cl, the tertiary amino group derived from cross-linker 7 contained a chloride anion as a hydrochloride, to some extent because hydrogen chloride was produced in the synthetic process of the polymer. Therefore, first, the chloride anion was exchanged for a nitrate anion by treatment with an excess amount of an aqueous sodium nitrate, and then, the amount of chloride anion newly released from the chlorotriazino group by treatment with NMM to form Poly-N-Trz-MM was determined according to the method mentioned above.
