Iminiumsions
Iminiumsions is a coined term used in speculative chemistry to describe proposed extended networks built from iminium centers linked into two- or three-dimensional frameworks. An iminium node arises from a positively charged nitrogen-containing center, typically described by a resonance form such as R2C=NR+. In this concept, such nodes serve as junctions that connect with covalent or noncovalent bridges to form delocalized, ion-rich structures. The term implies a hybrid between ionic character and extended conjugation, potentially yielding unique electronic and catalytic properties.
Structural motifs in iminiumsions are envisaged as arrays where iminium nodes are connected by polytopic linkers,
Synthesis routes in the concept range from in situ generation of iminium bonds via condensation of carbonyl
Properties often predicted for iminiumsions include tunable electronic structure, redox activity, and ionic conductivity, with potential
