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.COA of Formula: C47H36N4O

The authors report here the design and synthesis of porphyrin-metallocene dyads consisting of a metallocene [either ferrocene or mixed sandwich ¦Ç5-[C5H4(COOH)]Co(¦Ç4-C4Ph4)] connected via an ester linkage at meso Ph position of either free-base or Zn porphyrin. All these dyad systems were characterized by various spectroscopic and electrochem. methods. A dimeric form of these mols. was observed in the x-ray crystal structure of the zinc-porphyrin-cobaltocenyl dyad. The absorption spectra of all four dyads indicated the absence of electronic interactions between the porphyrin macrocycle and the metallocene in the ground state. However in all four dyads, fluorescence emission of the porphyrin was quenched (19-55%) as compared to their monomeric units. The quenching was more pronounced in ferrocene derivatives rather than cobaltocenyl derivatives The emission quenching can be attributed to the excited-state intramol. photoinduced electron transfer from metallocene to singlet excited state of porphyrin and the electron-transfer rates (kET) were established in the range 1.51 ¡Á 108 to 1.11 ¡Á 109 s-1. They are solvent dependent. This study involved multiple reactions and reactants, such as 4-(10,15,20-Tri-p-tolylporphyrin-5-yl)phenol (cas: 57412-08-5COA of Formula: C47H36N4O).
