Novel porphyrinoids explored in our laboratory in the past 15 years will be presented, which include meso-meso linked very long porphyrin arrays, triply linked extensively π-conjugated porphyrin tapes, porphyrin boxes, porphyrin wheels, porphyrin tubes, expanded porphyrins, and subporphyrins. A particular focus will be placed on Möbius aromatic and antiaromatic expanded porphyrins.
