Here we report on carbon monoxide-photoreleasable compounds (photoCORMs) that combine heptamethine cyanine and flavonol chromophores and are activated upon irradiation with near-infrared light. Excellent CO-release yields and uncaging cross sections in aqueoussolutions, enhanced water solubilities thanks to polar substituents or a host-guest approach using cucurbit[7]uril are demonstrated. The hybrids
在这里,我们报告了结合七次甲基花青和黄酮醇发色团并在用近红外光照射时被激活的一氧化碳可光释放化合物 (photoCORMs)。展示了优异的 CO 释放率和水溶液中的非封闭横截面,由于极性取代基或使用葫芦 [7] 脲的主客体方法而提高了水溶性。杂交体显示出出色的生物相容性和多样化的、结构依赖性的细胞渗透性和内化性。
