“…A typical approach involves the use of chromophores such as Pt(II) and Au(I) complexes. [15][16][17][18][19][20][21][22] These complexes can detect small lattice distortions induced by the adsorption of vapour through highly sensitive electronic transitions involving intermolecular metallophilic interactions. Other promising approaches recently developed involve the use of host-guest interactions between the adsorbing material and vapour molecules [23][24][25][26][27][28] or the use of ligand substitution reactions at metal centres.…”

A luminescent Pt(ii) complex [Pt(CN)(Hdpbpy)] (1P; Hdpbpy = 2,2'-bipyridine-4,4'-diphosphonic acid) bearing a phosphonic-acid-functionalized bipyridine ligand was successfully synthesized and its unique two-way vapochromic behaviour investigated. X-ray structure analyses of both the anhydrous 1P and penta-hydrated 1P·5H2O phases clearly reveal the activation of intermolecular PtPt interactions through the adsorption of water vapour. Emission spectroscopy reveals that the penta-hydrated 1P·5H2O complex exhibits an orange emission at 585 nm that shifts in two directions, to a blue-green emission at 469 nm by drying at 100 °C or to a red emission at 701 nm by drying under vacuum at room temperature. Thermogravimetric analyses and powder X-ray diffraction studies clearly reveal that anhydrous 1P, with negligible intermolecular PtPt interactions, is formed by drying at 100 °C whereas the monohydrate 1P·H2O phase, with effective PtPt interactions, is formed by drying under vacuum.

“…In 2017, Kuwabara et al 25 reported cationic Pt(II) isonitriles showing different emission colors upon varying counterions and solvents. Pt(II) isonitrile complexes with applications as catalysts, 26 hydrogels, 27 and vapoluminescence 28 have been disclosed as well. However, most reported Pt(II) complexes suffer from low emission yields and short lifetimes due to molecular aggregation.…”

Five Pt(II) complexes bearing a 3,6-di-tert-butyl-1,8-bis(1H-imidazol-1-yl)-9H-carbazole (BIMCA) backbone and different isonitrile ancillary ligands were synthesized and photophysically characterized. The solid-state structures were determined by X-ray crystallography, all of which showed a distorted-square-planar geometry where isonitrile moieties protrude from the Pt−carbazole plane. In the solid state, these complexes show biexponential phosphorescence with lifetimes up to 25 ms and quantum yields ranging from 5% to 22%. In solution, these complexes are weakly emissive with a nanosecond-scale lifetime. Density functional theory calculations indicate that the highest occupied Kohn−Sham orbital (HOMO) and the lowest unoccupied Kohn−Sham orbital (LUMO) reside primarily on the Me BIMCA ligand.

This work suggests a new method for extracting parameters from the current-voltage characteristics of photovoltaic (PV) panel to establish translational relations that allows to predict these PV parameters in other conditions of temperature and irradiation levels. This method is based on the knowledge of few selected points which are the short-circuit point, the maximum power point, and the open circuit point. These points are extracted from the current-voltage characteristics provided by the manufacturer's datasheet. Single diode model is chosen to represent the PV panel which is known as five parameters model. It includes two parasitic resistances, diode saturation current, diode ideality factor, and photo-current. The main results of simulations in Matlab environment show that the five PV parameters varies as function of irradiance and temperature. The proposed technique is compared to other published methods applied on Kyocera KC175GHT-2 PV panel. The obtained results show that the new suggested method of predicting PV parameters presents a lower statistical error whatever the weather conditions. Therefore, the new method is validated and more precise than extraction methods reported in the literature.
