We studied the supramolecular assembly of a multifunctional ligand, cis-bis-terpyridine tetraphenyl ethylene, on a Cu(111) surface by low-temperature scanning tunneling microscopy (STM). Three distinctive supramolecular structures, metallacycles, propeller-shaped clusters and extended linear chains, are formed under specific assembly conditions owing to different inter-molecular binding modes o...

A concise synthetic protocol for aryl functionalized phenanthrolines has been developed. It was demonstrated that 3,8-diphenyl-1,10-phenanthroline (7a) is competent in promoting transition-metal-free direct arylation and 2,3,8,9-tetraphenyl-1,10-phenanthroline (8a) is a highly efficient ligand in the in situ Pd-catalysed Heck reaction.

meso-Tetraphenylporphyrin N-oxide (1) and meso-tetraphenyl-21,23-dithiaporphyrin S-oxide (3) possess optical spectra that are distinctly different from their parent porphyrins, meso-tetraphenylporphyrin (2) and meso-tetraphenyl-21,23-dithiaporphyrin (4), respectively. The hyperporphyrin spectra were reproduced and classified using TD CAM-B3LYP and SCS-CC2 computational methods. Calculations rev...

Macrocyclic complexes of co(III) of the type, CoCy1-2B’X where Cy1 represents themacrocyclic ligand 1,8-dichloro-2,7,9,14-tetraoxa-1,1,8,8-tetraisopropoxy4,5,11,12-tetramethyl-1,3,6,10,13tetraaza, cyclotetradeca-3,5,10,12tetrene[boimacylene(14)] and cy2-represents the macrocyclic ligand 1,8-dibora2,7,9,14-tetraoxa -1,1,8,8-tetraisopropoxy 4,5,11,12-tetraphenyl-1,3,6,10,13Tetraazacyclotetradeca-...

the search for new stationary phases has been one of the predominant concerns in high performance liquid chromatography (hplc) in order to achieve better resolutions, longer column lives, and reduce the time of analysis. a chromatographic packing for separation of underivatized amino acids (aas) were prepared by dynamically coating 2-amino tetraphenyl prophyrin (atpp) on a c-18 reversed-phase p...
