New semiconducting polymer with alkoxy substituted terthiophene, as the electron rich unit, and 2,2-(1,5-pentamethylene)-2H-benzimidazole (PMBI), as the electron deficient unit, was synthesized using Stille polymerization. The advantage of PMBI is higher solubility of the polymer while keeping the coplanarity of the backbone as compared to the benzothiadiazole moiety of PCDTBT. In PMBI, the sulfur...
Intramolecular shifts in charge distribution have been investigated for the coordination polymers of [Co III (N-N) (SQ)(Cat)] n /[Co II (N-N)(SQ) 2 ] n tautomers (N-N = 4.4′-bipyridine analogs; SQ = 3.6-di-t-butyl- 1.2-semiquinone; Cat = 3,6-di-t-butylcatechol). The polymers remain exclusively in the low-spin Co III and high-spin Co II limiting...
