Rapp, T.L., Y. Wang, M.A. DeLessio, M.R. Gau, and I.J. Dmochowski, 2019: Designing photolabile ruthenium polypyridyl crosslinkers for hydrogel formation and multiplexed, visible-light degradation. RSC Adv., 9, no. 9, 4942-4947, doi:10.1039/C8RA09764J.

Photoresponsive materials afford spatiotemporal control over desirable physical, chemical and biological properties. For advanced applications, there is need for molecular phototriggers that are readily incorporated within larger structures, and spatially-sequentially addressable with different wavelengths of visible light, enabling multiplexing. Here we describe spectrally tunable (λ_max = 420-530 nm) ruthenium polypyridyl complexes functionalized with two photolabile nitrile ligands that present terminal alkynes for subsequent crosslinking reactions, including hydrogel formation. Two Ru crosslinkers were incorporated within a PEG-hydrogel matrix, and sequentially degraded by irradiation with 592 nm and 410 nm light.
