Perovskite solar cells (PSCs) have become a research hotspot since their dramatic increase in power conversion efficiency (PCE), surpassing 26% due to advances cell engineering and interfacial layers. Within the last factor, hole transporting materials play crucial role enhancing device performance stability. Among several molecular building blocks, BODIPYs are attractive for design of novel material (HTMs) outstanding photophysical charge transport properties easily tuned by synthetic modifications. Herein, synthesis five new BODIPY‐based HTMs PyBDP 1–5 reported, functionalized at meso‐ α‐ positions with pyrenyl arylamino units, respectively. The resulting compounds exhibit broad absorption visible region, remarkable thermal stability, narrow bandgaps, suitable energy levels, good extraction capability, as subtracted from experimental computational characterizations. BODIPY derivatives is evaluated planar inverted (p‐ i ‐n) PSCs compared commonly used PTAA, highly efficient systems, reaching PCEs very close that obtained reference polymer (21.51%). incorporation these result an PCE 20.37% devices including PyBDP‐1 19.97% devises containing PyBDP‐3 , thus demonstrating promising alternative obtain simple organic HTMs.

In this work, various novel pyridinyl- and pyridinium-modified Aza-BODIPY PSs were designed constructed based on monoiodo (BDP-4 BDP-15) in an attempt to construct "structure-inherent organelles-targeted" endow potential organelle-targeting ability. Pyridinyl displayed potent photodynamic efficacy, monorigidified very effective. The PS 20 with meta-pyridinyl moiety the most photoactivity negligible dark toxicity a favorable dark/phototoxicity ratio (>4800). To our surprise, (e.g., 20) was lipid droplet-targeted. showed good cellular uptake intracellular ROS generation compared BDP-15. preliminary cell death process exploration indicated that resulted peroxidation induced through iron-independent ferroptosis-like pathway. vivo antitumor efficacy experiments manifested significantly inhibited tumor growth outperformed BDP-15 Ce6 even under single low-dose light irradiation (30 J/cm2).
