Abstract

Herein, the synthesis of two chiral NPBIs, (S)-1 and (R)-1, is reported and their self-assembling features investigated. The reported NPBIs form chiral supramolecular polymers with a rich dichroic pattern by the pi-stacking of the aromatic backbones and the formation of an array of H-bonds between the amide functional groups. Furthermore, the peripheral 3,4,5-trialkoxy benzamide groups can form seven-membered pseudocycles by the intramolecular H-bonding interaction between the NH of the peripheral amides and one of the carbonyls of the imide units thus yielding a kinetically controlled self-assembly process. Unlike achiral NPBI 1, that has been reported to form up to four supramolecular polymorphs, the reported chiral NPBIs form only a J-type aggregated species. The results presented herein reveal how subtle changes exert an enormous influence on the supramolecular polymerization outcome.

Quality index

Bibliometric impact. Analysis of the contribution and dissemination channel

The work has been published in the journal CHIRALITY due to its progression and the good impact it has achieved in recent years, according to the agency WoS (JCR), it has become a reference in its field. In the year of publication of the work, 2024 there are still no calculated indicators, but in 2023, it was in position 42/72, thus managing to position itself as a Q1 (Primer Cuartil), in the category Chemistry, Medicinal.

Impact and social visibility

From the perspective of influence or social adoption, and based on metrics associated with mentions and interactions provided by agencies specializing in calculating the so-called "Alternative or Social Metrics," we can highlight as of 2025-07-04:

  • The use of this contribution in bookmarks, code forks, additions to favorite lists for recurrent reading, as well as general views, indicates that someone is using the publication as a basis for their current work. This may be a notable indicator of future more formal and academic citations. This claim is supported by the result of the "Capture" indicator, which yields a total of: 9 (PlumX).

With a more dissemination-oriented intent and targeting more general audiences, we can observe other more global scores such as:

    It is essential to present evidence supporting full alignment with institutional principles and guidelines on Open Science and the Conservation and Dissemination of Intellectual Heritage. A clear example of this is:

    • The work has been submitted to a journal whose editorial policy allows open Open Access publication.
