complexation reversible, it advantageously allows to repeatedly
use the polymeric Zn–porphyrin system for further chiral recogni-
tion. Work is in progress to assess the applicability of this system
to other classes of chiral compounds.

strated by color variation and spectroscopic analysis. In particular,
the CD spectra, initially silent, upon addition of optically active dia-
mine, show dichroic signals related to the electronic transitions of
the porphyrin chromophores, with a behavior typical of exciton
splitting determined by cooperative interactions between side-
chain porphyrin chromophores disposed in a mutual chiral geom-
etry of one prevailing handedness. Being the observed couplet sign
a direct consequence of the chirality of the diamine, which is trans-
mitted to a prevailing helical handedness of the interacting chro-
mophores, the assignment of chirality is nonempirical.

Although the CD signals displayed by this polymeric system re-
sulted four times lower in intensity with respect to low molecular
weight porphyrin tweezers previously reported in the literature, it
appears however very sensitive and convenient for chiral recogni-
tion, being the material easy to synthesize, thermally stable, and
requiring only few microgram quantities of the guest compound.
This example may open a new route for a general approach to
the design of polymeric systems to be applied in the field of chiral
recognition and absolute configuration assignment and could be
extendable to a large variety of chiral substrates.
