Abstract: Template effect of the solvents plays a key role in metal-organic frameworks (MOFs) synthesis. In addition, Bi3+ has a flexible and changeable coordination configuration, which is conducive to the construction of structurally diverse MOFs. Herein, we demonstrate that these features can be integrated into two stable bismuth-based porphyrin MOFs (named PFC-100 and PFC-101) with a wide range of light absorption. Further studies demonstrate that PFC-101 with weaker interactions of adjacent porphyrin planes achieves 22.2% photothermal conversion efficiency (PTCE), 1.5-fold higher than that of PFC-100 (14.3%) under 660 nm irradiation. This study may shed light on the impact of solvent templates on the synthesis of bismuth-based MOFs, not only enriching the MOFs library but also broadening the horizon of their potential applications.
