With the rise of anti-vascular endothelial growth factor antibody and programmed cell death-ligand 1 (PD-L1) regimens, particularly bevacizumab and atezolizumab, as first-line treatments for advanced hepatocellular carcinoma (HCC), there is a need to explore PD-L1 and programmed cell death 1 inhibitors in combination therapies for unresectable HCC (uHCC). Integrating systemic therapies with locoregional approaches is also emerging as a potent strategy. This study compares the outcomes of atezolizumab (PD-L1 inhibitor) and sintilimab (programmed cell death 1 inhibitor) with bevacizumab or its biosimilar, combined with hepatic arterial interventional therapies (HAIT) in uHCC patients.

Guangdong-Hong Kong Joint Laboratory for Carbon Neutrality, Jiangmen Laboratory of Carbon Science and Technology, Jiangmen, Guangdong, 529199, P. R. China.

Giant dimeric acceptors (GDAs), a sub-type of acceptor materials for organic solar cells (OSCs), have garnered much attention due to the synergistic advantages of their monomeric and polymeric acceptors, forming a well-defined molecular structure with a giant molecular weight for high efficiency and stability. In this study, for the first time, two new GDAs, DYF-V and DY2F-V are designed and synthesized for OSC operation, by connecting one vinylene linker with the mono-/di-fluorinated end group on two Y-series monomers, respectively. After fluorination, both DYF-V and DY2F-V exhibit bathochromic absorption and denser packing modes due to the stronger intramolecular charge transfer effect and torsion-free backbones.
