Entry point into new trimeric and tetrameric imide-based macrocyclic esters derived from isophthaloyl dichloride and methyl 6-aminonicotinate
No full textThe one-step reaction of isophthaloyl dichloride with the 2-aminopyridine derivative (methyl 6-aminonicotinate) yields (i) a trimer-based macrocycle (EsIO)3 and (ii) a tetramer-based macrocycle (EsIO)4 in modest isolated synthetic yields (total of 25%), together with (iii) longer open-chain oligomers. The macrocyclisation relies on the semi-flexible imide hinge formed by reaction of the 2-amino(pyridine) functional group with two acyl chloride functional groups. The determining factors in macrocycle synthesis are (a) imide formation using the heteroaromatic ortho-N functionality; (b) the inherent ability of the imide to twist by 85-115 degrees from planarity (as measured by the CO...CO imide torsion angles and from computational calculations), thereby providing a hinge for macrocyclic ring closure or potentially (non)helical assembly in oligomer/polymer formation and (c) the conformational flexibility of the isophthaloyl group with meta-related carbonyl groups to twist and adopt either syn- or anti-conformations, although the syn-conformation is observed structurally for all isophthaloyl groups in both (EsIO)3 and (EsIO)4 macrocycles
Marcia Gallagher and Mrs. T. B. Heffington

Miss Gallagher is her successor as a program director and supervisor of women\u27s and children\u27s work. They are sitting o a couch, facing each other. Miss Gallagher is wearing a polka dot dress with a lace collar and a charm bracelet on her right wrist and watch on her left wrist. Mrs. Heffington is wearing a solid-colored dress with buttons down the bodice, and a ring on her ring finger on her left hand.https://mavmatrix.uta.edu/specialcollections_startelegram1940s/4074/thumbnail.jp
Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
