Protoporphyrin IX diester

Result to 2 Thermal copolymerisaticm of styrene with the vinyl groups in methylpheophorbid-a (S6) or protoporphyrin-IX diesters (7f) in a molar ratio of lO - 10 1 gives polymers (17) (18) they are soluble in toluene and stable in HO. 

Fe(II, III)-protoporphyrin-IX-diester (7 c, d) with poly(N-vinyl)-imidazole)41 42), polystyrene (in mixture with l-(2-phenyl-ethylimidazole)43). 

Two older reviews summarize work in this field [124,125]. The following derivatives have been employed as porphyrins Fe(II,III) protoporphyrin-EX (heme, hemin), Fe(II,III) or Co(II) protoporphyrin-IX-diester, chlorophyllins with different metal ions in the core, Fe(II) tetraphenylporphyrin, Mg(II) or Fe(II,III) octaethylporphyrin, Fe(II,III) tetrakis[o-(alkylamido)phenyl]-porphyrin. Polymers with N-donor groups are based on proteins such as poly(L-lysine), poly(L-histidine), poly(Y-benzyl-L-glutamate) or synthetic polymers such as homopolymers and copolymers with vinylpyridine, iV-vinylimidazole or ethyleneimine. 

Due to the many biological functions of ferrous heme nitrosyls, many corresponding model complexes have been synthesized and structurally and spectroscopically characterized, viz. tetraphenylporphyrin (TPPH2), octaethylporphyrin (OEPH2) and protoporphyrin IX diester (PPDEH2), ms o-tetrakis (4-carboxyphenyl) porphyrin (TCPP), meso-tetrakis [4-(N,N,N-trimethyl) aminophenyl] porphyrin (TTMAPP),...
