Provided is a method of manufacturing a bipyridinium compound denoted by general formula (A).
In general formula (A), Ar
1
and Ar
2
each independently denote an optionally substituted (hetero)aryl group, R
3
and R
4
each independently denote a substituent that may form a ring with a pyridine ring to which the substituent substitutes, m3 and m4 each independently denote an integer ranging from 0 to 4, X denotes a halogen atom or RSO
3
, and R denotes an optionally substituted aryl group or alkyl group. The method can manufacture a 4,4′-bipyridinium compound under mild reaction conditions in an integrated manner without separation of intermediates.

The π bonds between organic radicals have generated excitement as an orthogonal interaction for designing self‐assembling architectures in water. A systematic investigation of the effect of the viologen cationradicalstructure on the strength and nature of the pimer bond is provided. A striking and unexpected feature of this π bond is that the bond strength is unchanged by substitution with electron‐donating
