Protonated rubyrin and C-Tips: Co-carriers for the transport of guanosine 5′-monophosphate at neutral pH

Abstract
At neutral and near-neutral pH, rubyrin, a readily protonated, hexapyrrolic expanded porphyrin, and triisopropylsilyl-protected cytidine (C-Tips) act cooperatively to effect the efficient through-transport of guanosine 5′-monophosphate (GMP) in a model three-phase H2O-CH2Cl2-H2O bulk liquid membrane system.
