Here, it is reported that organic field-effect transistors (OFETs) with n-type conjugated polymer, poly[{2,5-bis-(2-octhyldodecyl)-3,6-bis-(thien-2-yl)-pyrrolo[3,4-c]pyrrole-1,4-diyl}-co-{2,2′-(3,4-dinitrothiophene)]-5,5′-diyl}] (PODTPPD-DNT), can be operated without large disturbance by surrounding light. The PODTPPD-DNT polymer synthesized via the Stille coupling reaction could act as a channel layer for n-channel OFETs. Although the PODTPPD-DNT polymer shows a broad optical absorption from UV to near-IR parts up to 1000 nm, the OFETs with the PODTPPD-DNT channel layers do not almost respond to monochromatic (520 and 780 nm) and white light. The reason is assigned to the exciton quenching effect by two nitro groups in the polymer chain. The semitransparent OFETs with the 20 nm thick PODTPPD-DNT channel layers are also almost light-insensitive for operation under typical room light conditions.
