By a News Reporter-Staff News Editor at Science Letter -- Research findings on Supramolecular Research are discussed in a new report. According to news originating from Bengal, India, by NewsRx correspondents, research stated, "The cooperative effect of weak non-covalent forces between anions and electron deficient aromatics by pi...pi stacking of a series of carbene proligands (1-3) have been thoroughly explored by crystallographic studies. Structural analysis revealed that the anion...pi and pi...pi interactions along with intermolecular hydrogen bonding mutually cooperate to facilitate the assembling of the supramolecular framework."

Our news journalists obtained a quote from the research from Bengal Engineering and Science University, "The pi...pi and corresponding anion...pi interactions have been investigated in the title carbene proligands despite their association with counter ions. The presence of the anion in the vicinity of the pi-system leads to the formation of anion...pi/pi...pi/pi...anion network for an inductive stabilization of the assemblies. To assess the dimensionality of the supramolecular framework consolidated by cooperative anion...pi/pi...pi interactions and hydrogen bonding, different substituent effects in the carbene backbone have been considered to tune these interactions. These facts show that the supramolecular framework based on these cooperative weak forces may be robust enough for application in molecular recognition. The investigation of close intermolecular interactions between the molecules via Hirshfeld surface analyses is presented in order to reveal subtle differences and similarities in the crystal structures."

According to the news editors, the research concluded: "The decomposition of the fingerprint plot area provides a percentage of each intermolecular interaction, allowing for a quantified analysis of close contacts within each crystal."
