概要（目的・用途・実施内容）/ Abstract (Aim, Use Applications and Contents)
2D-Covalent Organic Frameworks containing layered structures have gained significant attention due to their tunable porous structures and physical properties. First mesoporous two- dimensional covalent organic framework, known as COF-5, exhibits hexagonal pores with a diameter of 2.7 nm. It was produced through polycondensation reactions involving diboronic acid (BDBA) and hexahydroxy triphenylene (HHTP) building blocks. Afterward, the first p-type semiconducting COFs were reported. In 2011, imine linkage containing conductive covalent organic frameworks (COFs) was first reported. The carrier mobilities of this imine-linked COF have been claimed to be almost comparable to polycrystalline silicon. We have synthesized two dimensional Covalent Organic Frameworks with two donar building blocks in this work.
実験 / Experimental
For the structural characterization of the newly synthesized COFs we have used PXRD, FT-IR, UV-Vis. We have also used SEM, TEM for the morphological characterization. Finally FP-TRMC measurement has been done to analyze their conductive properties.
結果と考察 / Results and Discussion
From the PXRD, FT-IR, and UV-Vis we have confirmed the successful formation of Covalent Organic Frameworks. The SEM and TEM images also support the ordered growth. We observed that after I2 doping the conductivity enhanced by 10 folds compared to pristine in FP-TRMC measurement.
