DOI: 10.1007/s12045-019-0798-0
Abstract: Alkyl groups can delocalize both the negative and positive charges through ion (charge)-induced dipole interaction with the polarizable alkyl groups. This charge induced polarization of the alkyl group to delocalize the charge is the origin… read more here.

Abstract: Abstract Association constants and single-ion conductivities of the bromide salts of five isomeric tetrabutylammonium ions were determined with dilute-solution conductivity measurements for aqueous solutions at 298.15 K. In addition, for two of the isomers dielectric relaxation… read more here.

DOI: 10.1021/acs.orglett.6b03428
Abstract: Two novel β-hexaalkylated porphycenes, i.e., 2,3,7,12,13,17- (HOT) and 2,3,6,12,13,16-hexaethylporphycenes (HIT) were introduced for the first time in porphycene chemistry. These were synthesized through McMurry coupling reactions of new isomeric unsymmetrically substituted triethylbipyrrole dialdehydes. The positional… read more here.
