Solvent free synthesis of a novel intermolecular compound and its crystal structure, thermal and optical studies

Forecast of Phase Diagram for the Synthesis of a Complex for the Detection of Cr6+ Ions

“…The finding is clearly apparent from Table . The observed large shifting explains that when an electron-donating group (amino group) and an electron accepting group (carbonyl group) combines either directly or through a bridge of conjugated double bonds, the migration of electrons is possible from the former to the latter, and subsequently, the complex gives rise to a special absorption band totally different from the parent components. − The variation in the absorption maxima and the fluorescence have been plotted in terms of Lippert–Mataga solvent polarity parameter (Δ f ) which is a function of the dielectric constant (ε) and refractive index (η) of the solvents. , where …”

Solid-Liquid Equilibrium Study for Binary System Forming Intermolecular Compound: Phase Diagram, Thermal, Physicochemical and Powder XRD study

“…The difference between experimental and theoretical values gives the enthalpy of mixing (∆ mix H) which predicts the nature of interaction in the binary melt. As such, three types of structures are suggested: quasi-eutectic for ∆ mix H> 0, clustering of molecules for ∆ mix H< 0 and molecular solution for ∆ mix H = 0 [10][11][12]. The system shows the negative and positive ∆ mix H values for E 1 and E 2 inferred clustering of molecules and quasi-eutectic, respectively, in the eutectic melt.…”
