Abstract

A new imine-based covalent organic framework (COF) functionalized in its cavities with moieties of the chromophore Nile Red has been synthesized and characterized. Using mechanical (ultrasonics) and chemical (acid-self-exfoliation) methods, exfoliation of the COF powder has been explored in water and water/organic media. In the latter, the obtained colloids exhibit dual emission originating from the Nile Red units (red) and the COF framework (green) that can be employed to prepare ratiometric sensors of polarity and acidity. Thus, taking advantage of the in situ exfoliation of the material in methacrylic monomers, free-standing polymeric films that preserve the optical properties of the exfoliated COF have been prepared. Finally, 3D liquid crystal display (LCD) additive manufacturing has been employed to prepare the dual emissive composites as tailored 3D-printed objects.

Quality index

Bibliometric impact. Analysis of the contribution and dissemination channel

The work has been published in the journal Journal of Materials Chemistry A 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, 2022, it was in position 32/344, thus managing to position itself as a Q1 (Primer Cuartil), in the category Materials Science, Multidisciplinary. Notably, the journal is positioned above the 90th percentile.

From a relative perspective, and based on the normalized impact indicator calculated from World Citations provided by WoS (ESI, Clarivate), it yields a value for the citation normalization relative to the expected citation rate of: 3.04. This indicates that, compared to works in the same discipline and in the same year of publication, it ranks as a work cited above average. (source consulted: ESI Nov 14, 2024)

This information is reinforced by other indicators of the same type, which, although dynamic over time and dependent on the set of average global citations at the time of their calculation, consistently position the work at some point among the top 50% most cited in its field:

  • Weighted Average of Normalized Impact by the Scopus agency: 4.04 (source consulted: FECYT Feb 2024)
  • Field Citation Ratio (FCR) from Dimensions: 5.34 (source consulted: Dimensions Jul 2025)

Specifically, and according to different indexing agencies, this work has accumulated citations as of 2025-07-20, the following number of citations:

  • WoS: 21
  • Scopus: 23

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 2025-07-20:

  • The use, from an academic perspective evidenced by the Altmetric agency indicator referring to aggregations made by the personal bibliographic manager Mendeley, gives us a total of: 24.
  • 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: 24 (PlumX).

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

  • The Total Score from Altmetric: 7.8.
  • The number of mentions on the social network Facebook: 1 (Altmetric).
  • The number of mentions on the social network X (formerly Twitter): 14 (Altmetric).
