, p. 12955 - 12959 (2009)
Expand your horizon: BODIPY-appended [28]-and [26]hexaphyrins (see figure) were prepared and the efficient intramolecular excitation energy transfer from the BODIPY part to the hexaphyrin part was revealed in both hybrids. Importantly this is the first ex

We have explored the electronic natures of representative expanded porphyrins, [26]- and [28]-hexaphyrins, to investigate the interplay between the aromaticity and antiaromaticity that is brought by two electron oxidation/reduction processes. The excited

A strong correlation among calculated Nucleus-Independent Chemical Shift (NICS) values, molecular planarity, and the observed two-photon absorption (TPA) values was found for a series of closely matched expanded porphyrins. The expanded porphyrins in ques

(Chemical Equation Presented) A series of meso-porphyrinyl-substituted expanded porphyrins were prepared from the 1:1 acid-catalyzed condensation reaction of 4-porphyrinyl-2,3,5,6-tetrafluorobenzaldehyde and pyrrole.
A new reagent for the synthesis of [26]hexaphyrin: N-sulfonyl aldimine

supporting information, p. 544 - 547 (2014/01/06)
The selective synthesis of [26]hexaphyrin(1.1.1.1.1.1) has been achieved by the reaction of meso-substituted tripyrrane and N-sulfonyl aldimine. The protocol is simple and requires only a catalytic amount of copper(II) triflate under mild reaction conditions.

experimental part, p. 1341 - 1349 (2009/04/06)
Acid-catalyzed condensation of meso-pentafluorophenyl dipyrromethane 1 (100 mM) and pentafluorobenzaldehyde 2 (100 mM) at 0 °C gave a series of expanded porphyrins with even number of pyrrolic subunits up to octadecaphyrin-(1.1.1.1.1.1.1.1.1.1.1.1.1.1.1.1.1.1) 18 in improved yields, particularly for larger expanded porphyrins. The solid-state structure of decaphyrin(1.1.1.1.1.1.1.1.1.1) 10 was revealed by X-ray diffraction analysis to be a crescent-like conformation. The Soret-like absorption bands are increasingly redshifted as the size of the ring increases, but such a trend becomes nearly saturated for hexadecaphyrin-(1.1.1.1.1.1.1.1.1.1.1.1.1.1.1.1) 16 and 18, which exhibit bands in the near-infrared region at 939 and 953 nm, respectively.
