## Abstract The preparation of novel highly water‐soluble electrostatic complexes from C~60~‐anchored multi‐armed poly(acrylic acid)s and cationic porphyrin derivatives was demonstrated. The UV‐vis absorption and photoluminescence (PL) of these complexes show that the absorption of soret band exhib

✦ Synopsis
these coordination compounds. Deviating from the photochemistry of the regular (coplanar) metalloporphyrins, the out-of-plane structure and the kinetic lability of the SAT complexes facilitate the photodissociation as well as the separation of the primary products of the photoinduced LMCT reaction, promoting an irreversible ring-opening of the oxidized porphyrin.

4 homologous series of watersoluble porphyrins was prepared by reacting diamiics of the type HIN(CHt),NH&z = 2,3,4, 6) with pmtoporphyrin IX dimethyl ester. There was addition of a diamine to each vinyl group and replacement of the alcohol moiety of each ester group by a diamine. The dimerization of
The kinetics of zinc incorporation from pH 12 to 13 into the centrally aprotic BrP (4)^2+^ form of beta-octabromo-meso-tetrakis(N-methyl-4-pyridyl)porphyrin and its monolithium complex were studied at 25.0 °C, ionic strength (I) = 0.10. The reactions were first order in porphyrin and total zinc conc
Abatraet-A series of water-soluble zinc porphyrins, ZnTPPS, ZnTPPC and ZnTPPOH, have been synthesized. Their absorption, emission, singlet and triplet state quenching by electron acceptors like MVZf and 1,5-AQDS\*-have been studied in homogeneous aqueous solutions and bound to a PVP matrix. Binding
