1,3,5,7-Tetrasubstituted adamantanes as frameworks in the design of assemblies of porphyrin macrocycles

Abstract

A new strategy for the synthesis of adamantane-containing polyphenols of a porphyrin series has been suggested on the basis of Suzuki–Miyaura reaction between 1,3,5,7-tetrakis(4'-iodophenyl)adamantane and a monoboryl derivative of substituted porphyrin. The synthesis of this porphyrin assembly on the adamantane core followed by chemical transformations of this compound has provided a possibility to synthesize the corresponding polyphenol derivative. The latter has been used in the development of positive photoresists for nanolithography with exposure to radiation at a wavelength 13.5 nm capable of producing topological structures with a resolution of 16 nm.
