Key Points

To develop a method for selectively reducing pyridinium groups in organic cages while preserving hydrazone bonds.
Performed postsynthetic modification of hexacationic organic cages
Executed a single-step reduction reaction to convert pyridinium rings to tetrahydropyridines
Assessed sulfate binding of the modified neutral cages
Achieved high-yielding conversion of pyridinium rings to 1,2,3,6-tetrahydropyridines
Successfully maintained the integrity of the hydrazone C═N bond
Demonstrated strong sulfate binding properties in the new neutral cages

Abstract

Postsynthetic modification of a series of hexacationic organic cages containing pyridinium and hydrazone groups gave a new family of neutral organic cages through a high-yielding single-step reduction reaction. The reaction selectively reduces all six pyridinium rings to 1,2,3,6-tetrahydropyridines but leaves the hydrazone C═N bond untouched. The neutral cages display strong sulfate binding to give cage·(SO
