Abstract: Abstract The replacement of conducting layers in known layered superconducting compounds is a significant challenge in the search for novel superconductors. In particular, the exploration of superconductors can be accelerated by combining the application of high pressure for modifying the crystal structure. In this study, we investigate the electrical transport properties of the layered CuSe-based compound BiOCuSe, which has the same structure as the 1111-type iron-based superconductor La(O,F)FeAs, under high pressure exceeding 80 GPa. In addition, as related CuSe-based compounds, the electrical properties of YBi2O4Cu2Se2 and Cu2Se are measured under high pressure. Although no clear signatures of bulk superconductivity are observed in these CuSe-based compounds, filamentary superconductivity emerges in BiOCuSe and Cu2Se. Given the rapid advancements in high-pressure techniques in recent years, further exploration of high-pressure effects on layered materials with novel conducting layers is expected to lead to the discovery of next-generation superconducting materials.
