Abstract
5,7,8,10-Tetraphenyl-1,14-di(arylamino)tripyrrins have been synthesized via 5,7,8,10-tetraphenyltripyrrane. The structures and dynamic equilibrium between single helical monomer and double helical dimer were analyzed by 1H NMR spectra and X-ray diffraction analysis. Their dimerization association constants in CDCl3 are larger than those of previously reported dianilinotripyrrin derivatives. In DMSO, they exhibited luminescence around 700 nm as a consequence of restricted rotational relaxation by the phenyl groups installed at the 7,8-positions.

- 25 It was difficult to determine the dimerization association constants for 4a and 4b in CDCl3 because of almost complete association (i.e., Kd >103). A small difference between 4a and 4b might be ascribed to the steric repulsion between the trifluoromethyl group and tripyrrin core.
- 26 A preliminary measurement for the fluorescence lifetime using time-correlated single photon counting technique revealed the lifetime of 0.75 ns for 4b. See SI for details.
