The incorporation of an electron-accepting unit into π-conjugated systems is an important approach to modulate the physical properties of such molecules. To investigate the potential of tetrazolo[1,5

We have investigated the effects of the preparation conditions of polythiophene/graphene complexes on their dispersion in organic solvents, and on the in-solution morphology of the multilayered graphene. Among four different regioregular polythiophen

Recently, the synthesis of P3HT with high head-to-tail regioregularity and the control of the molecular weight have been achieved. Herein, we evaluated the structure in thin films of various molecular weight P3HT (from M w = 13 k to 828 k) prepared u

Polythiophenes bearing a siloxane moiety in a substituent at the 3-position are prepared by deprotonative polycondensation of 2-bromo-3-substituted-thiophene with a bulky magnesium amide chloromagnesium 2,2,6,6-tetramethylpiperidine-1-yl lithium chlo

Polymerization of 2,4-dibromo-3-hexyl-5-lithiated thiophene that is formed by deprotonation of 2,5-dibromo-3-hexylthiophene with LDA and following halogen dance takes place in the presence of a nickel(II) or palladium(II) catalyst to afford poly(3-br

Cross-coupling polycondensation of thiophene derivatives occurs via C–S bond cleavage in the presence of a nickel catalyst. Head to tail type (HT) regioregular poly(3-hexylthiophene) is obtained by a nickel(II)-catalyzed deprotonative C–H functio

Revisiting Murahashi coupling, we found that it effectively allows polymerization of lithiated (hetero)arenes by nickel(II)-catalyzed polycondensation. Deprotonative polymerization of 2-chloro-3-substituted thiophene with n-butyllithium gave head-to-

Deprotonative metalation of chlorothiophene takes place with a catalytic amount of cis-2,6-dimethylpiperidine (DMP) and an alkyl Grignard reagent at room temperature for three hours to give the corresponding thienyl Grignard reagent. Polymerization l
