二维范德华异质结构（2D vdWhs）因其有趣的物理性质而受到人们的极大关注，这些物理性质由组成的单层及其层间耦合严格定义。基于化学可调谐单层有机二维材料合成二维 vdWh 仍然具有挑战性。在此，报道了通过将π-共轭二维配位聚合物（2DCP，即Cu ₃ BHT，BHT = 苯六硫醇）与石墨烯相结合来制备新型有机-无机双层vdWh。使用水面化学合成具有可检测的 µm ²尺度均匀性和原子平坦度的单层 Cu ₃ BHT。衍射和成像技术的结合能够以原子精度测定单层 Cu ₃ BHT 的晶体结构。利用强层间耦合，Cu ₃ BHT-石墨烯 vdWh 表现出高效的光致层间电荷分离，从 Cu ₃ BHT 到石墨烯的净电子转移效率高达 34%，优于报道的双层 2D vdWh 和分子石墨烯 vdWh 。这项研究揭示了开发具有有趣物理特性的新型基于 2DCP 的 vdWh 的潜力。
