The phys. and electronic properties of nano-scale semiconductor devices are mainly decided by their surfaces and interfaces. Use of dipolar self-assembled monolayer (SAM) on semiconductor/oxide interfaces has an enormous potential to tailor the behavior of nanoelectronic, optical and biol. devices. Among different mols., porphyrins have been identified to form chem. stable SAMs on different substrates and their dipolar properties can be tuned by incorporating various metal species in them. This allows work-function tuning according to various technol. needs. In this paper, we describe the effect of central metal ion (selected period-4 transition metal ions Zn, Cu, Ni, Fe and Co) incorporated in 5-(4-hydroxyphenyl)-10,15,20-tri(p-tolyl)porphyrin (TTPOH) on the surface potential using Kelvin probe microscopy. D. functional theory (DFT) calculations were performed to estimate the magnitude of dipole moments. Also, absorption spectra of TTPOH mol. and its metal derivatives are compared. This study involved multiple reactions and reactants, such as 4-(10,15,20-Tri-p-tolylporphyrin-5-yl)phenol (cas: 57412-08-5Electric Literature of C47H36N4O).
4-(10,15,20-Tri-p-tolylporphyrin-5-yl)phenol (cas: 57412-08-5) belongs to catalyst ligands. Ligand design occupies a central place in organic synthesis and catalysis. And they often provide a convenient approach to fine-tuning the performance of known catalysts.Electric Literature of C47H36N4O
