Abstract
A new strategy for the synthesis of monodisperse polyphenols chemically bound to a rigid thermally stable molecular platform has been suggested. The platform has been prepared by the Suzuki–Miyaura reaction of a tetraboryl porphyrin derivative and 3-(4′-bromophenyl)-4,6-dimethoxyindole. Subsequent reactions of complete demethylation of obtained tetraindole and partial blocking of the corresponding phenolic hydroxyls by acid-labile protective groups have led to the formation of a final modified polyphenol compound of the porphyrin series. On the basis of the this polyphenol, a positive photoresist for lithography with exposure radiation at a wavelength of 13.5 nm has been developed; the photoresist affords the fabrication of topological structures with 16-nm resolution.
