    摘要: This invention provides approaches to improve the signal to noise ratio (S/N) in electrochemical measurements (e.g. amperometry, voltammetry, etc.). In particular, a method is described wherein the faradaic current is temporally dissociated from the charging current associated with reading the charge of a redox-active species (e.g. a self-assembled monolayer (SAM)). This method, designated herein as open circuit potential amperometry (OCPA), quantitatively reads the charge of the redox species bound to (electrically coupled to) an electrode surface, while discriminating against both charging current(s) and amperometric signal(s) that arise, e.g. from diffusion-based species in solution.

    摘要: A method of making a porphyrin is carried out by: (a) condensing (i) a 1,9-bis(N,N-)dialkylaminomethyl)dipyrromethane of Formula II: with (ii) a dipyrromethane to produce a reaction product; then (b) oxidizing the reaction product; and then (c) optionally demetallating said reaction product to produce the porphyrin. The reaction is particularly useful for making substituted porphyrins with a wide range of substituents at the A and/or B (the 5 and/or 15) positions.

    摘要: A method of making a metalloporphyrin is carried out by reacting (i) a linear tetrapyrrole, said linear tetrapyrrole having a 19-acyl group and a 1-protecting group, with (ii) a metal salt under basic conditions to produce the metalloporphyrin. Products produced by such methods and intermediates useful for carrying out such methods are also described.
