The development of portable X-ray detectors is necessary for diagnos.ng fractures in unconscious patients in emergency situations. however, this is quite challenging because of the heavy weight of the scintillator and silicon photodetectors. The weight and thickness of X-ray detectors can be reduced by replacing the silicon layer with an organic photodetectors. This study presents a novel bithienopyrroledione-based polymer donor that exhibits excellent photodetection properties even in a thick photoactive layer (similar to 700 nm), owing to the symmetric backbone and highly soluble molecular structure of bithienopyrroledione. The ability of bithienopyrroledione-based polymer donor to strongly suppress the dark current density (J(d) similar to 10(-10) A cm(-2)) at a negative bias (-2.0 V) while maintaining high responsivity (R = 0.29 A W-1) even at a thickness of 700 nm results in a maximum shot-noise-limited specific detectivity of D-sh* = 2.18 x 10(13) Jones in the organic photodetectors. Printed organic photodetectors are developed by slot-die coating for use in X-ray detectors, which exhibit D-sh* = 2.73 x 10(12) Jones with clear ris.ng (0.26 s) and falling (0.29 s) response times upon X-ray irradiation. Detection reliability is also proven by linear response of the X-ray detector, and the X-ray detection limit is 3 mA.
