摘要

Abstract Disymmetrically substituted oligo (phenyleneethynediyl)(OPE) derivatives were prepared from 2, 5-bis (octyloxy)-4-[(triisopropylsilyl) ethynyl] benzaldehyde (5) by an iterative approach using the following reaction sequence: i) Corey–Fuchs dibromoolefination, ii) treatment with an excess of lithium diisopropylamide, and iii) a metal- catalyzed cross-coupling reaction of the resulting terminal alkyne with 2, 5-diiodo-1, 4-bis ( ...
