Intrinsic Photo-Crosslinkable Semiconductive Small-Molecule Crystals (i-PSSCs) for Patterning Electronic Devices.

ABSTRACT: Precise patterning of small-molecule semiconductive crystals without external chemical additives remains a significant challenge. Herein, intrinsic photo-crosslinkable semiconductive small-molecule crystals (i-PSSCs) are designed and synthesized by associating [1]benzothieno[3,2-b]benzothiophene core with diacetylene-ended groups. The i-PSSCs undergo self-crosslinking directly upon UV light irradiation to yield micron-scale patterned crystalline films through a combination of photo-crosslinking and solvent rinsing. The molecular packing remains intact before and after patterning. Therefore, the electrical performance of the organic thin-film transistors fabricated from both pristine and patterned i-PSSCs films shows minimal difference, with maximum field-effect mobilities of 0.46 and 0.25
