Boron-bridged poly(ferrocenylene)s as promising materials for nanoscale molecular wires
摘要:
The ferrocene-containing polymer [-fc-B(Br)-](n) (6) with an average chain length of ca. 20 repeat units (n = 20) is readily accessible from fc(BBr2)(2) and HSiEt3 [fc = (C5H4)(2)Fe] via a novel polycondensation reaction. Treatment of 6 with excess THF yields the highly soluble alkoxy-substituted derivative [-fc-B(O(CH2)(4)Br)-](n) (10; n = 20). (c) 2006 Elsevier B.V. All rights reserved.
