Nanocrystallization of organic molecular photosensitizers (PSs) by means of NMOF platforms has been demonstrated to be a promising approach to build up highly efficient PDT therapeutics. We report herein a new UiO-66 type of NMOF-based PS (UiO-66-TPP-SH), which is generated from UiO-66 NMOF and S-ethylthiol ester monosubstituted metal free porphyrin (TPP-SH) via a facile postsynthetic approach under mild conditions. The obtained NMOF (size less than 150 nm) with surface-decorated porphyrinic PS can not only retain MOF crystallinity, structural feature, and size, but also exhibit highly efficient singlet oxygen generation. Compared to the interior-located porphyrinic NMOF, UiO-66-TPP-SH shows significantly higher photodynamic activity and more efficient PDT tumor treatment.
通过 NMOF 平台对有机分子光敏剂 (PSs) 进行纳米结晶已被证明是构建高效 PDT 治疗方法的一种很有前途的方法。我们在此报告了一种新型基于 UiO-66 类型的 NMOF 的 PS（UiO-66-TPP-SH），它是通过在温和条件下通过简便的后合成方法从 UiO-66 NMOF 和 S-乙基硫醇酯单取代无金属卟啉 (TPP-SH) 生成的。所得的具有表面修饰卟啉 PS 的 NMOF（尺寸小于 150nm）不仅保留了 MOF 的结晶度、结构特征和尺寸，而且还表现出高效的单线态氧生成。与位于内部的卟啉 NMOF 相比，UiO-66-TPP-SH 表现出更高的光动力活性和更有效的 PDT 肿瘤治疗效果。
