Figure | Overview of organic small-molecule NIR-II fluorophores for tumor phototheranostics. This figure summarizes representative molecular scaffolds, including cyanine, BODIPY, benzobisthiadiazole, xanthene, cyano-based derivatives, and small-molecule metal complexes, alongside rational design strategies such as NIR-II molecule design, targeted molecule design and activatable molecule design. These approaches enable tunable emission profiles and optimized photophysical properties. Collectively, these advances facilitate deep-tissue bioimaging and effective phototherapeutic modalities.
