However, it's still a big challenge to develop novel mitochondrial-targeting photosensitizers, especially those that possess better performance than traditional TPP-modified photosensitizers. In this work, three cationic boron-dipyrromethene (BODIPY) nanoparticles with different mitochondrial-targeting groups (triphenylphosphine, trimethylamine and 1-methylimidazole) were designed and synthesized for enhanced photodynamic therapy. These BODIPY nanoparticles (BDPI NPs) could be endocytosed by various cancer cells and dissociated in the lysosomes. Subsequently, they escaped from the lysosomes due to the “proton-sponge” effect and were enriched on the inner membrane of mitochondria for enhanced photodynamic therapy. BDPI NPs could generate not only singlet oxygen (<small>¹</small>O<small>₂</small>) but also superoxide anions (O<small>₂</small><small>⁻</small>˙), showing great type I and II photodynamic activity. Compared with TPP and the trimethylamine substitution, the 1-methylimidazole-modified nanoparticles (BDPI-IMA NPs) exhibited the most efficient mitochondrial-targeting capability and the most excellent photodynamic activity.

Different from polyanionic compounds, there is no direct connection between anions within heteroanionic compounds. The connectivity between anions and central atoms constitutes various distorted basic building units (BBUs). The linkage between BBUs further promotes the structural flexibility of heteroanionic compounds. The diverse bonding modes of anion–metal interactions, which originate from the various physical and chemical properties of anions, explain the existence of many important applications of heteroanionic compounds. In this short review, we summarize the synthesis, structures, and physical applications of selected heteroanionic compounds. From a synthesis perspective, a deep understanding of crystal growth mechanisms and a better controlled growth process should be emphasized in future research. The interactions between distinct anions and other featured elements such as elements with lone electron pairs, d<small>⁰</small> and d<small>¹⁰</small> transition metals, <em>etc.</em>, or other systems such as high entropy systems would further promote more interesting applications.
