By introduction of electron-withdrawing groups such as fluorine atoms on the 4- and 6-positions of 2-phenylpyridyl (ppy) and using strong-field ligands for instance PPh and pseudohalogen as ancillary ligands, the HOMO–LUMO electronic energy gaps of and have been increased sufficiently. The ...
Write the electron configuration in {eq}{{t}_{2g}}\text{ }and\text{ }{{e}_{g}} {/eq} orbitals in an octahedral field for {eq}{{Mn}^{2+}} {/eq} metal ions with strong ligand field strength. Strong Field Ligand: ...
Weak field ligands are low spin complexes while strong field ligands are high spin complexes. Answer and Explanation: Low spin complexes: t2g are completely filled then after that seventh electron will en...
owing to parity-forbidden transitions at the bandgap energy20. Addressing these challenges to achieve strong optical absorption near the band edges would optimize the performance of these materials in ultrathin PV cells – a promising new frontier in the field of renewable energy research, which redu...
is remarkable, especially considering that molecular capping ligands were presented, as can be seen from the TEM measurements in Supplementary Fig.3. Previous experiments on Au nanowires have measured quality factors for damping by the surfactant layer ofQ_{{\mathrm{surf}}} \approx 20019,39, ...
It is however much harder to anticipate the sign of the couplings for geome- tries with two bridging ligands and bond angles close to 90°. Illustrative recent examples are the 5d hon- eKyictaoemvbansyissotetmrospyNKa2IarrOe3inantednsLeil2yIrdOe3b. aTthede signs of the NN Heisenberg in...
Strong-fieldligandThe emission λmax are strikingly shorter (451, 482 nm) for the cationic dicarbonyl complex [Ir(ppy)2(CO)2]+ (2a) than those (473, 495 nm) of the anionic dicyano complex [Ir(ppy)2(CN)2]–, where CO and CN– are both sp carbon coordinating ligands and known to ...

The ligands tested included partially and fully methylenephosphonated diethylenetriamine. In Table I the methylenephosphonated diethylenetriamines are represented by DT-4-MP, DT-3-MP and DT-2-MP which are partially phosphonomethylated diethylenetriamines containing an average of 4, 3 and 2 moles of...
