Synthesis, heterogenization and sensing properties of melamine-bridged bis-porphyrin dimers

A straightforward, "one-pot" approach to the construction of a new class of molecular tweezers and their heterogenization onto various aminated materials is reviewed here. It is based on nucleophilic substitution of the cyanuric chloride scaffold with tailored aminoporphyrin subunits. The molecular recognition properties of these porphyrinic materials for diamine sensing are also discussed.
