Density, viscosity, and speed of sound data for (sulfolane + ethyl acetate (EA)), (sulfolane + n-propyl acetate (PA)), and (sulfolane + n-butyl acetate (BA)) were determined at T ) (303.15 to 313.15) K. From this data, excess molar volume and deviation in isentropic compressibility, ∆κ s , have been calculated. The computed properties were fit to a Redlich-Kister polynomial.

This paper presents a 10-step synthetic route for the preparation of a series of new back-to-back coupled 2,6-bis(pyrazol-1-yl)pyridine (bpp) ligands (L0-L3) decorated with tetraoctyl chains. Ligand L1 self-assembles with Zn(2+) ion to form a highly soluble metallo-supramolecular polymer 1 with M(n) ∼ 9600 g/mol. To demonstrate the processability of polymer 1, by following a "top-down" approach periodic one-dimensional fluorescent microstripes were fabricated on a silica substrate.

The excess isentropic compressibilities are computed by measuring the density and speed of sound of binary mixtures of N-methylacetamide with ethyl acetate, ethyl chloroacetate, and ethyl cyanoacetate over the entire range of volume fraction in the temperature range of (303.15 to 318.15) K. The experimental results are fitted to a Redlich-Kister type polynomial equation. Estimated coefficients and standard deviation values are also presented.
