However, how the topology of porphyrinic MOFs affects the generation of singlet oxygen (<jats:sup>1<\/jats:sup>O<jats:sub>2<\/jats:sub>) is unclear. Here, the effect of the topology of porphyrinic MOFs on their photodynamic performance is reported. Four porphyrinic zirconium MOFs (MOF\u2010525, MOF\u2010545, PCN\u2010223 and PCN\u2010224 with different topologies: <jats:bold>ftw<\/jats:bold>, <jats:bold>csq<\/jats:bold>, <jats:bold>shp<\/jats:bold> and <jats:bold>she<\/jats:bold>, respectively) were selected to study the influence of topology on the photodynamic antibacterial performance. The <jats:sup>1<\/jats:sup>O<jats:sub>2<\/jats:sub> generation and the photodynamic antibacterial performance followed an decreasing order of MOF\u2010545&gt;MOF\u2010525&gt;PCN\u2010224&gt;PCN\u2010223. The results reveal that the pore size, the distance between porphyrin, and the number of porphyrin per Zr<jats:sub>6<\/jats:sub>O<jats:sub>8<\/jats:sub> cluster in MOFs greatly affected <jats:sup>1<\/jats:sup>O<jats:sub>2<\/jats:sub> generation.
