Synthesis of diketopyrrolopyrrole based conjugated polymers containing thieno[3,2-: B] thiophene flanking groups for high performance thin film transistors
New donor-acceptor (D-A) conjugate polymers based on 3,6-bis(2-bromothieno-[3,2-b]thiophen-5-yl)-2,5-bis(2-octyldodecyl)pyrrolo[3,4-c]-pyrrole-1,4-(2H,5H)-dione (Br-TTDPP) combined with three different electron-donating monomers bithiophene (BT), di(2-thienyl)ethene (TVT), and di(selenophene-2-yl)ethene (SVS) were synthesized. The optical band gap, electrochemical properties and organic field-effect transistor (OFET) device performance of the TTDPP-based polymers were systematically investigated. X-ray diffraction (XRD) was used to evaluate the molecular packing of the TTDPP-based polymers. Among three polymers, TTDPP-SVS showed the smallest d-spacing and the largest distance of 0.372 for pi-pi stacking. In particular, an OTFT having a TTDPP-SVS active layer showed the highest hole mobility of 0.196 cm2 V-1 s-1, the lowest threshold voltage down to -3.6 V, and the highest Ion/Ioff ratio of 6.5 ¡Á 104. This indicates that pi-extended SVS significantly improves charge transport properties.
We¡¯ll also look at important developments in the pharmaceutical industry because understanding organic chemistry is important in understanding health, medicine, the role of 52409-22-0, and how the biochemistry of the body works.Application of 52409-22-0
