We report here the design and synthesis of a covalently linked stacked tetra porphyrin oligomer, which has been a challenging task so far. The interlinking phenanthroline units and several intramolecular H-bondings help the molecule fold in a sheet-like structure with three cleft-like cavities that bind two electron-deficient guests with high binding constant.
