The different natures of the weakly coordinating anions –triflate or perchlorate–in the Cu2+-mediatedself-assembly of cytidine monophosphate nucleotide play a fundamental role in the homochiralresolution process, yielding one-dimensional copper(II) coordination polymers of opposite helicity that can be easily inverted, in a reversible way, by changing the nature of the anion as revealed by circulardichroism experiments both in solution and in the solid state.

Abstract
The different natures of the weakly coordinating anions –triflate or perchlorate–in the Cu2+-mediatedself-assembly of cytidine monophosphate nucleotide play a fundamental role in the homochiralresolution process, yielding one-dimensional copper(II) coordination polymers of opposite helicity that can be easily inverted, in a reversible way, by changing the nature of the anion as revealed by circulardichroism experiments both in solution and in the solid state.File in questo prodotto:
