Photoresponsive control-release supramolecular systems have aroused considerable interest for the application in drug delivery, ion transport and so on. Here, we fabricated a stiff-stilbenes-based bis-urea that resembles a molecular tweezer, exhibiting reversible photoisomerization behaviors between (Z)-form and (E)-form. Significantly, photo-controlled selective recognition and release of CH₃CO₂⁻ and H₂PO₄⁻ were achieved by the molecular tweezer upon irradiation with distinct light. Furthermore, the stiff-stilbenes-based bis-urea also hold a functionalization as a novel photoinduced fluorescence switch. These finds have enormous potential for the application in optically controlled drug delivery, the regulation of anion transport across the cell membrane and advanced optical materials.

光响应性控释超分子系统引起了人们对于药物输送，离子迁移等方面的广泛关注。在这里，我们制造了一种类似于分子镊子的，基于硬方苯二甲酸酯的双脲，在（Z）-型和（E）-型之间表现出可逆的光异构行为。显著，光控选择性识别和CH的释放₃ CO ₂ ^-和H ₂ PO ₄ ^-当用不同的光照射时，通过分子镊实现。此外，基于硬方苯二酚的双脲还具有作为新型光诱导荧光开关的功能。这些发现对于光控药物输送，调节跨细胞膜的阴离子运输和先进的光学材料的应用具有巨大的潜力。
