title: Meso-beta doubly linked Zn(II) porphyrin trimers: distinct anti-versus-syn effects on their photophysical properties.
abstract: Meso-beta doubly linked Zn(II) porphyrin dimer 1 and anti- and syn-trimers 2 and 3 were synthesized by DDQ-Sc(OTf)(3) oxidation of the corresponding meso-beta singly linked porphyrin precursors. The absorption and fluorescence spectra and TPA cross-section values of 2 and 3 are distinctly different, reflecting their molecular shapes.
