A series of conjugated polymers containing alternating electron-donating and electron-accepting units based on thiophene and pyrazole groups. These polymers (PPZVT, PPZVT-BT) were synthesized via Yamamoto and stille coupling reactions. The synthesized polymers were well dissolved in common organic solvents, such as chloroform, THF and chlorobenzene. Thin solid films of PPZVT and PPZVT-BT exhibited the UV-visble absorption maxima at round 430nm. These polymers possess an optical band gap both 2.54eV from the absortion onset through UV-Vis spectro- scopy. Electrical band gap of PPZVT, PPZVT-BT was investigated 2.29, 2.35eV, respectively, through cyclic voltammetry. |
