Abstract
Two porous organic/inorganic microporous polymers (TPE-DDSQ POIP and Car-DDSQ POIP) were prepared through the Sonogashira-Hagihara coupling reaction of DDSQBr with 1,1,2,2-tetrakis(4-ethynylphenyl)ethene (TPE-T), and 3,3´,6,6´-tetraethynyl-9,9´-bicarbazole (Car-T); respectively. The chemical structure and properties of these two materials including thermal stability, porosity, crystallinity, and morphology were characterized in detail by using various instruments. Based on TGA analyses, Car-DDSQ POIP exhibited high thermal degradation temperature up to 439 °C and char yield up to 77.4 wt.% because inorganic DDSQ unit could enhance the thermal stability as expected. The electrochemical results revealed that TPE-DDSQ POIP and Car-DDSQ POIP showed specific capacitance of 22 and 23 F g−1 at 1 A g−1; respectively in a three-electrode with KOH solution (6 M) as electrolyte and capacitance retention at about 93% after 2000 galvanostatic charge–discharge cycles.
