And the article was included in Chinese Journal of Chemistry in 2010.Quality Control of 4-(10,15,20-Tri-p-tolylporphyrin-5-yl)phenol The following contents are mentioned in the article:
Porphyrin- or Zn-porphyrin-cyanuric acid conjugants (TPP-CA or ZnTPP-CA) and anthraquinone connected with the known Hamilton receptor (AQ-H) were synthesized. The supramol. dyads constructed via the AQ-H and TPP-CA/ZnTPP-CA exhibit 6 H bonds, which provide the association constant KAPP approx. (2.8 ¡À 0.3) ¡Á 103 mol-1/L in toluene. Selective excitation of the porphyrin/Zn porphyrin chromophores results in an electron transfer between TPP-CA/ZnTPP-CA and AQ-H within the supramol. assemblies, leading to an efficient quenching of the TPP-CA/ZnTPP-CA fluorescence. The singlet electron transfer from porphyrin/Zn-porphyrin to anthraquinone proceeds mainly via a through space mechanism with efficiencies of 43%, 58%, and rate constants of 7.6 ¡Á 107, 7.0 ¡Á 108 s-1, resp. This study involved multiple reactions and reactants, such as 4-(10,15,20-Tri-p-tolylporphyrin-5-yl)phenol (cas: 57412-08-5Quality Control of 4-(10,15,20-Tri-p-tolylporphyrin-5-yl)phenol).
