The semiconductor single-walled carbon nanotube(s-SWCNT)bound by the conjugated polymers(CPs)can act as channels in thin-film transistors(TFTs)with high charge mobility and good photoelectric re-sponse property,which shows huge utilization potential in artificial intelligence.Two CPs of 10Th-oCz-2,7-PM15 and 10Th-oCz-3,6-PM15 based on dibenzophenazine derivatives with different chain configuration were constructed by changing joining site between dibenzophenazine derivatives and carbazole.Among them,the 10Th-oCz-2,7-PM15 shows better effect of binding to s-SWCNT,owing to its planar conjugated configuration.Moreover,the TFT based on s-SWCNT bound by 10Th-oCz-2,7-PM15 presents better performance,for exam-ple,higher charge mobility of 10.58 cm2/V·s and bigger on/off ratio of 106.In conclusion,the configuration of CPs can influence the performance of TFT based on s-SWCNT bound by CPs eventually.
