“…The ability of nucleobases to self‐assemble through hydrogen bonds and π stacking is the basis for the formation of natural functional architectures that include duplex, triplex, and quadruplex structures, as well as artificial supramolecular systems, such as DNA origami . Interactions between nucleobases have also been successfully exploited for the preparation of charge‐transfer complexes, nonlinear optical single crystals, and nanomaterials . The attachment of nucleobases to low‐molecular‐weight poly(tetrahydrofuran) produces materials that show high melting temperatures and mechanical stability; chain‐end conjugation of nucleobases to oligomethylene results in the formation of hydrogels .…”

Studies carried out in recent decades have revealed that the ability to self‐assemble is a widespread property among biomolecules. Small nucleic acid moieties or very short peptides are able to generate intricate assemblies endowed with remarkable structural and spectroscopic properties. Herein, the structural/spectroscopic characterization of aggregates formed by nucleobases and peptide nucleic acid (PNA)–peptide conjugates are reported. At high concentration, all studied nucleobases form aggregates characterized by previously unreported fluorescence properties. The conjugation of these bases, as PNA derivatives, to the dipeptide Phe–Phe leads to the formation of novel hybrid assemblies, which are characterized by an amyloid‐like association of the monomers. Although these compounds share the same basic cross‐β motif, the nature and number of PNA units have an important impact on both the level of structural order and the intrinsic fluorescence of the self‐assembled nanostructure.

“…Within the 3100-2300 cm −1 range, 13 different hydrogen vibrations are absorbed. Furthermore, studies have documented vibrations of hydrogen bonds formed by water molecules at approximately 2342 and 2328 cm −1 .The bending modes of N-H[49] and OH, respectively, are responsible for the two prominent bands at 1725 cm −1 . Bands falling between 1611 and 1333 cm −1 are thought to be stretched triazine rings.…”

The controlled slow evaporation process conducted at room temperature has yielded a novel hybrid material designated as (2-hydroxyethyl) trimethylammonium dihydrogen phosphate [2-HDETDHP] (C5H14NO+, H2PO4−), cultivated through the solution growth method. X-ray crystallography analysis indicates that the material adopts a triclinic structure with a filling rate of P\(\stackrel{-}{1}\)and a Z value of 2. This hybrid material exhibits significant absorption characteristics in the middle and far ultraviolet regions, UV-visible spectroscopy revealed that it remained transparent in the visible and near-visible ultraviolet domains. The various vibration modes were examined using FT-IR spectroscopy, and their relationships with the functional groups of the related structure were determined. Two- and three-dimensional fingerprint maps, along with three-dimensional using crystal Structures through Hirshfeld Surface Analysis, elucidate that O•••H and H•••H interactions dominate the structure, constituting the major proportions of 49.40% and 50.40%, respectively. Hirshfeld surfaces were employed to investigate intermolecular hydrogen bonding specifically within single phosphate groups. Fingerprint plots derived from the Hirshfeld surface were utilized to assess the pertinent percentages of hydrogen bonding interactions, with 80.6% of them being attributed to a fragment patch. This discovery holds potential implications for the future design and synthesis of large nonlinear optical (NLO) hybrid crystals.
