The investigation of the 12.21 phanes by spectroscopIc methods provides tnformation on the transannular Intramolecular 1T-electron interaction through space, since in these molecules the two aromatic units arc kept in a face-to-face arrangement with well defined distance by methylene bridges. Additiol1ai jnforrn~tion on the influence of the orientation of the two subunits with respect to each o...

3,7,23,27-Tetrabromo[36]octaphyrin 2 was synthesized as a novel octaphyrin bearing two meso-free positions. Surprisingly, its ZnII and NiII complexation reactions produced directly fused porphyrin(2.1.1.1) dimer 6, meso-α N-confused porphyrin (NCP) 7, the first example of NCP tape, respectively, via transannular C−C bond formation. While 6 exhibits diatropic ring-current effect owing to global ...
