Abstract: Owing to the incidental crosslinking reaction of monomer, the as-prepared poly(divinyldioxythiophene (PEDOT) always has poor electric conductivity and difficult subsequent processing. Thus, it is very important to develop appropriate polymerization method to synthesis PEDOT. Poly(divinyldioxythiophene has been synthesized via free radical oxidation polymerization in the one-dimensional channel of indium p-phthalic coordination polymer (In-BDC) metal organic framework material (MOF) as a reactive template to form PEDOT@In-BDC composite. The PEDOT@In-BDC composites were characterized by XRD, SEM, FTIR, TG and N₂-sorption isotherm analysis. The results show that the monomer conversion of divinyldioxythiophene (EDOT) is higher than 91%. During the polymerization reaction, the framework of In-BDC template keeps constant. The specific surface area (BET) value of PEDOT@In-BDC composite is 45 m²/g. Compared with In-BDC template, PEDOT@In-BDC composites obtained by free radical oxidation polymerization of monomer divinyldioxythiophene in MOF are more stable. The result of current-voltage (I-V) linear scan test indicates that the PEDOT@In-BDC composite is novel semiconductor material and conductive based on PEDOT. The conductivity of PEDOT@In-BDC composite reaches 2.7×10⁻⁵ S/m. Compared with the functional porous material In-BDC (10⁻¹² S/cm) , the PEDOT@In-BDC composite has higher electric conductivity and is at least six orders higher than that of In-BDC template.
