## Description

- description: Precise patterning of small-molecule semiconductive crystals without
    external chemical additives remains a significant challenge. Herein, we design
    and synthesize intrinsic photo-crosslinkable semiconductive small-molecule crystals
    (i-PSSCs) by associating [1]benzothieno[3,2-b]benzothiophene core with diacetylene-ended
    groups. The i-PSSCs undergo self-crosslinking directly upon ultraviolet 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
    show minimal difference, with maximum field-effect mobilities of 0.46 and 0.25
    cm² V-¹ s-¹, respectively. Moreover, the i-PSSCs in a transistor array exhibit
    high sensitivity and selective response to ultraviolet patterns, enabling bio-inspired
    vision systems that mimic human retinal extraction of image descriptors. This
    work offers a valuable strategy for developing i-PSSCs for UV-selective artificial
    vision applications.
