Two isomers of porphyrin trimer with 1,4-diaryltriazole linkers have been synthesized using click methodology and characterized by MS, NMR and UV-vis spectroscopy. The porphyrin compounds were shown to exhibit photostability and high solubility. Photophys

The synthesis and characterization of organometallic oligomers of the type [(p-C6H4)C≡CPt(P(nBu)3) 6C≡C(p-C6H4)-Zn(P)]n with the corresponding models [(C6H5C≡C)R(P(n-Bu)3) 2C≡C(p-C6 H4)Zn(P)(p-C6H 4)C≡CR(P(n-Bu)3)2(C≡CC 5H5)], where Zn(P) is zinc(11)-10,20-di(mesityl)- (n = 4, 9) or zinc(11)-10,20-di-n-pentyl-porphyrin (n = 3, 6, 9), are reported. The electronic spectra (absorption, excitation, emission, and transient absorption) and the photophysical properties (emission lifetimes and quantum yields) of these species in 2-methyltetrahyrofuran at 298 and 77 K are presented. Rates for triplet (T1) energy transfer, kET, from the [(p-C 6H4C≡C)Pt(P(n-Bu)3)2(C≡ C-p-C6H4)] spacer to Zn(P) vary from 2.4 × 10 4to 1.3 × 106 s-1. For the n-pentyl case, a rate dependence of oligomer size is noted as kET increases with the number of units, n. This phenomenon is interpreted by the presence of an excitonic process (i.e., delocalization of the energy along the Zn(P) array).
One-step template-directed synthesis of a macrocyclic tetraarylporphyrin hexamer based on supramolecular interactions with a C3-symmetric tetraarylporphyrin trimer

Taking into consideration the model geometry of the macrocyclic hexaporphyrin 1 as a host molecule, the structure of a benzene-centered porphyrin trimer bearing pyridine rings at the apical positions has been designed with the aim to use the latter as a t
