Unprecedented self-sorting of three-dimensional purely organic cages driven by dynamic covalent bonds is described. Four different cages were first synthesized by condensation of two triamines and two dialdehydes separately. When a mixture of all the comp

Phenylethynyl-bridged dipyrrin "dimers" have performed ZnII complexation to give coordination polymers, which provided the fluorescent colloidal spherical objects in solution as well as on the substrate according to the spacer units. Using a mi

A set of bis(phenylethynyl)phenylene-bridged diporphyrins 1-3 has been prepared by the acid-catalysed double condensation reaction of bis(4-formylphenylethynyl)benzene 8 and 9, and 3,5-di-ferf-butylbenzaldehyde 11 with bis(3-hexyl-4-methylpyrrol-2-yl)methane 12 or the Pd0-catalysed coupling reaction of acetylene-substituted porphyrin 14 with 1,4-diiodobenzene. Intramolecular singlet excitation energy transfer in Zn-free base hybrid diporphyrins 1-3(ZH) has been studied by picosecond time-resolved fluorescence spectroscopy. The determined kEN values are in the order of 1(ZH) > 2(ZH) ≈ 3(ZH). The energy transfer mechanism is discussed in terms of varying contribution of through-space and through-bond interactions.
