A photolabile ruthenium-based complex, Ru(bpy) (4AMP) , (4AMP=4-(aminomethyl)pyridine) is incorporated into polyurea organo- and hydrogels via the reactive amine moieties on the photocleavable 4AMP ligands. While showing long-term stability in the dark, cleavage of the pyridine-ruthenium bond upon irradiation with visible or near-infrared irradiation (in a two-photon process) leads to rapid de-gelation of the supramolecular gels, thus enabling spatiotemporal micropatterning by photomasking or pulsed NIR-laser irradiation.
一种光不稳定的基于钌的配合物，Ru(bpy)(4AMP)，（4AMP=4-（氨甲基）吡啶），通过光可裂解的 4AMP 配体上的反应性胺部分掺入聚脲有机和水凝胶中。虽然在黑暗中表现出长期稳定性，但在可见光或近红外光照射下（在双光子过程中）裂解吡啶-钌键会导致超分子凝胶迅速去凝胶化，从而通过光掩模或脉冲近红外激光照射实现时空微图案化。
