Synthesis, characterization, and solid-state polymerization properties of two diacetylene derivatives containing phenyl ferrocene

Two diacetylene complexes, 1,4-bis(3- ferrocenylphenyl)- 1,3-butadiyne(4a) and 1,4-bis(4-ferrocenylphenyl)-1,3- butadiyne (4b), have been prepared. The solid-state polymerization properties of 4a and 4b were also investigated.
