In this module we’ll first discuss liquids in the context of the other two main states of matter, solids and gases. These varied behaviors arise primarily from the different types of intermolecular forces that are present in liquids. You may also notice a similar phenomenon in some salad dressings that separate into an oil layer that rests atop a layer of vinegar, which is primarily water. Consider oil spills, where the oil floats in a sticky, iridescent layer on top of the water. Others, though, don’t seem to mix at all. When it comes to interactions between different liquids, some mix well: Think of a Shirley Temple, made of ginger ale and grenadine. Where do these different behaviors come from? Some liquids flow relatively easily, like water or oil, while others, like honey or molasses, flow quite slowly. Beyond this feature, though, the behaviors of different liquids span a broad range. One of the key defining properties of liquids is their ability to flow. These are just three examples of a highly diverse state of matter: liquids.

Y-Chromsome and Mitochondrial DNA Haplotypes.Absorción, distribución, y almacenamiento de químicos.El Descubrimiento y Estructura de Células.The presented tunable luminescent soft materials obtained through noncovalent supramolecular approaches will open a new avenue in the fields of optoelectronic organic materials. This red-shifted emission can be attributed to the stabilization of the excited intramolecular charge transfer state of the donor–acceptor luminophore by polar molecules. Modulation of the emission color from light-blue to blue-green in the liquid-crystalline states has been achieved by incorporating the ionic liquid. The co-assembly of oxadiazole derivatives and nonvolatile 1-butyl-3-methylimidazolium-based ionic liquids through hydrogen bonding leads to the formation of thermally stable nanosegregated columnar structures with confined channels of ionic liquids. These molecules exhibit strong solvatochromism depending on the solvent polarity. Luminescent oxadiazole-based columnar liquid crystals containing a diethanolamine moiety forming intramolecular donor–acceptor charge transfer states have been designed and synthesized.
