In this paper, we investigate the humidity sensing properties of an organic dye material (E)-2-(4-(2-(3,4-dimethoxybenzeylidene)hydrazinyl)phenyl)ethane-1,1,2-tricarbonitrile (DMBHPET). The sensors were fabricated by making pairs of aluminum electrodes on glass substrates. The gap between the electrodes was 40 lm. The active layer was deposited in the gap using the drop casting technique. The r...
The use of an alkane mixture that remains liquid at 77 K to freeze specimens has advantages over the use of a pure alkane that is solid at 77 K. It was found that a mixture of methane and ethane did not give a cooling rate adequate to produce vitreous ice, but a mixture of propane and ethane did result in vitreous ice. Furthermore, the latter mixture produced less damage to specimens mounted on...
The introduction of the combination of open metal site (OMS) and π-complexation into MOF has led to very high ethylene-ethane adsorption selectivity at 318 K, as illustrated in the context of MIL-101-Cr-SO3Ag. The interactions with ethylene from both OMS and π-complexation in MIL-101-Cr-SO3Ag have been investigated by in situ IR spectroscopic studies and computational calculations, which sugges...
Direct partial oxidation of methane, ethane, and propane to their respective trifluoroacetate esters is achieved by a homogeneous hypervalent iodine(III) complex in non-superacidic (trifluoroacetic acid) solvent. The reaction is highly selective for ester formation (>99%). In the case of ethane, greater than 0.5 M EtTFA can be achieved. Preliminary kinetic analysis and density functional calcul...
Three solid-state supramolecular structures were obtained by inclusion complexation of p-sulfonatocalix[5]arene with 1,2-bis(4,40-methylpyridinium)ethane, 1,2-bis(4,40aminopyridinium)ethane and 1,4-bis(pyridinium)butane. All three complexes have been thoroughly examined from the aspects of binding mode, stoichiometry and extended structure. Effects of guest molecules, especially spacers and ter...
