And the article was included in Journal of the Chemical Society, Chemical Communications in 1992.Safety of 4-(10,15,20-Tri-p-tolylporphyrin-5-yl)phenol The following contents are mentioned in the article:
Two [2]rotaxanes, composed of (i) a polyether chain intercepted by (a) one centrally-located and (b) two sym. ¦Ð-electron-rich hydroquinol rings and terminated by free-base and metalized (Zn) tetraaryl-porphyrin groups resp. and (ii) a tetracationic cyclophane constructed of two ¦Ð-electron-deficient bipyridinium units linked by paraphenylenedimethyl residues, have been self-assembled by a clipping procedure. This study involved multiple reactions and reactants, such as 4-(10,15,20-Tri-p-tolylporphyrin-5-yl)phenol (cas: 57412-08-5Safety of 4-(10,15,20-Tri-p-tolylporphyrin-5-yl)phenol).
4-(10,15,20-Tri-p-tolylporphyrin-5-yl)phenol (cas: 57412-08-5) belongs to catalyst ligands. A ligand is an ion or molecule, which donates a pair of electrons to the central metal atom or ion to form a coordination complex. Precious metals and metal oxides on carrier materials are used in many industrial processes as heterogenous catalysts.Safety of 4-(10,15,20-Tri-p-tolylporphyrin-5-yl)phenol
