摘要:
A method of making a metal complex comprises combining a 1-monoacyldipyrromethane with a compound of the formula R1R2MX, wherein M is boron, R1 and R2 are each independently organic substituents; and X is an anion leaving group; to produce a metal complex of the formula DMR1R2 wherein DH is a 1-monoacyldipyrromethane. The methods and complexes are useful for the purification and synthesis of dipyrromethanes and porphyrins.
摘要:
A method of making chlorins comprises the steps of reacting (e.g. condensing) a dipyrrin western half intermediate with an eastern half intermediate to form a tetrahydrobilene, and then cyclizing the tetrahydrobilene to form a chlorin. Intermediates including tetrahydrobilenes useful in such reactions are also described.
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 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.

The present invention provides compounds of the general Formula DI: along with methods of making such compounds, formulations containing the same, and methods of using the same (e.g., in photodynamic therapy, for the production of solar cells, etc.).
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 compound of Formula I: is carried out by condensing a pair of compounds of Formula II (which pair may be the same or different), or by condensing a compound of Formula III with a compound Formula IV, to produce a compound of Formula I. The condensing step may be carried out with a metal salt under basic conditions.
