Jul 1, 2023 · Inspired by the base-pairing in the DNA double helix, Meijer et al. developed the self-complementary quadruple hydrogen bonding unit ureidopyimidinone (UPy), which has a strong dimerization constant (Kdim > 10 7 M −1 ).

Ureido-heterocycles exhibiting different triple- and quadruple H-bonding patterns are useful building blocks in the construction of supramolecular polymers, self-healing materials, stimuli-responsive devices, catalysts and sensors.

Feb 28, 2024 · The authors made the serendipitous observation that a compound known as ureidopyrimidinone glycine (UPy–Gly) polymerizes in solution to form short fibres, which then promote a condensation...

Aug 1, 2012 · Ureidopyrimidone (UPy) formed a self-complementary dimer via quadruple hydrogen-bonding (DDAA-AADD) with a remarkably strong self-association constant (Ka>10 7 l mol –1).

In this report, we describe the circularly polarized luminescence (CPL) of the RNA duplexes having one to four 2'-O-pyrene modified uridines (Upy) and the DNA duplexes having two, four, and six pyrene modified non-nucleosidic linkers (Py).

Mar 29, 2021 · Supramolecular biomaterials based on ureido-pyrimidinone (UPy) moieties are versatile polymer materials as their function can be tailored to the application. These UPy-materials can be designed into polymer coatings, self …

Nov 1, 2022 · The obtained UPy derivatives containing self-complementary quadruple hydrogen bonding interactions can spontaneously self-assemble towards the formation of well-controlled, self-organized supramolecular nanostructure morphologies in both chloroform and water.

Sep 1, 2019 · The ubiquity of easily synthesized, yet potent hydrogen bonding functional groups including amides, ureas, urethanes, ureido-pyrimidinones (UPy), and DNA base pairs offers diverse options for the design of supramolecular gelators.

ureidopyrimidinone glycine (UPy–Gly) polymerizes in solution to form short fibres, which then promote a condensation process that produces high-density phases contain-ing supramolecular...

They assembled 2-ureido-4 [1H]-pyrimidinone (UPy) units into extended chains by means of quadruple cooperative hydrogen bonds in an array and developed products with similar mechanical properties that until then could only be achieved with covalent polymers (Fig. 1.1).
