title: Endocyclic extension of porphyrin pi-system in etheno-bridged N-confused tetraphenylporphyrin.
abstract: Etheno-bridged N-confused tetraphenylporphyrin was synthesized through flipping of the confused pyrrole ring and endocyclic extension of [18]annulenic pi-conjugated system was exemplified by the absorption spectra as well as the calculated Kohn-Sham orbitals.
