A new type of porphyrin array (I) (R = Me, OC16H33) has been synthesized by the coupling of six porphyrin moieties to a central benzene core via an ether linkage. The resulting porphyrin supermol. has a diameter up to 80 ? and a mass of 8500 daltons. In solution, the six porphyrins around the central benzene ring arrange themselves into three sets of offset overlapping dimers, which are rapidly interconverting at room temperature Solution UV-vis and fluorescence studies, however, indicate that there are no electronic interactions between the individual porphyrin mols. Upon spreading a chloroform solution of these porphyrin mols. on a surface, they self-assemble to form ring-shaped architectures on a micrometer scale. Near-field scanning optical microscopy studies reveal that the porphyrin moieties within the rings have an ordered arrangement with respect to their position in the ring after the sample has been annealed at 80 ¡ãC for 2 days. 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. Ligands, especially phosphines and carbenes, can play a key role in modifying and controlling homogeneous organometallic catalysts. Chiral compounds with high purities and ee values are often used as ligands for catalytically active metal complexes. Safety of 4-(10,15,20-Tri-p-tolylporphyrin-5-yl)phenol
