Metal-Organic Frameworks: Synthesis and Applications

A radical result. Viologen embedded in the walls of the mesoporous silica (see graphic) forms less stable charge-transfer complexes than when adsorbed onto MCM-41 and with a red-shifted λmax. The as-synthesized material thermally generates the corresponding radical cation.
