Abstract

Bowl-shaped aromatics that self-assemble into columnar liquid crystals (LCs) are key components for developing polarized semiconductors. However, progress in this field has been sluggish, as the limited set of available pi-conjugated curved scaffolds has left structure-property relationships poorly understood. Herein the role that substitution pattern, substituent nature, and chirality play in the LC columnar organization of subphthalocyanines (SubPcs) is explored. Remarkably, it is revealed that enantiopure SubPcs exhibit a reduced tendency to form LC phases compared to their racemic counterparts, whereas higher substitution density increases flexibility within the columns, compromising coaxial alignment. Moreover, we find that the use of conformationally flexible, pi-extended peripheral substituents enables efficient pi-pi stacking, and that the incorporation of hydrogen-bonding amide groups leads to highly stable mesophases with elevated melting points, although the mesophase remains at room temperature after thermal treatment. These trends are further rationalized through theoretical modeling. Overall, this work provides valuable synthetic and design guidelines for advancing bowl-shaped aromatics toward next-generation functional columnar liquid crystals.

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 2026-04-05:

  • 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: 1.
  • 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: 1 (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: 4.
  • The number of mentions on the social network X (formerly Twitter): 8 (Altmetric).

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.
  • Assignment of a Handle/URN as an identifier within the deposit in the Institutional Repository: https://repositorio.uam.es/handle/10486/720976
