Viologen-templated bromoplumbate: a new in situ synthetic method and energy gap engineering
Changing N -substituents to modify energy gaps is important for the diverse applications (photochromism, photocatalysis, etc. ) of viologen-based compounds.

In situ N
-substitution using alcohols under solvothermal and acidic conditions is an effective and common synthetic method for viologen-templated metal halides. In this work, we found that replacing alcohols with alkenes could reduce the reaction temperature dramatically to room temperature. A new
