Tetrathiafulvalene Porphyrins

Chemistry – A European Journal, 2008
AbstractFour tetrathiafulvalene (TTF)‐annulated porphyrins 1–4 were synthesized and characterized. All contain a tetraphenylporphyrin (TPP) core onto which four, two, or one TTF subunits were annulated. Absorption and fluorescence spectroscopic studies together with electrochemical investigations reveal that interactions between the porphyrin system ...

Self-assembly of porphyrin–azulene–porphyrin and porphyrin–azulene conjugates

Organic & Biomolecular Chemistry, 2009
In this paper we report the synthesis and self-assembling behavior of new porphyrin-azulene-porphyrin and porphyrin-azulene conjugates. The porphyrin-azulene-porphyrin conjugate gelates a number of organic solvents, while the porphyrin-azulene conjugates form vesicles in a chloroform-methanol binary mixture.

Porphyrins, porphyrin metabolism and porphyrias. I. Update

Scandinavian Journal of Clinical and Laboratory Investigation, 2000
The biosynthesis of porphyrins is one of the most conserved parthways known, about the same sequence of reactions taking place in all species. By associating different metals, porphyrins give rise to the "pigments of life": chlorophyll, haem and cobalamin.
