Herein, a novel two-dimensional (2D) halogen-bonded organic framework (XOF–TPPE) was successfully designed and fabricated by iodonium-bridged N⋅⋅⋅I + ⋅⋅⋅N interactions between pyridyl groups and I + for the first time.

2024年12月6日 · In this study, we report the development of a novel two-dimensional radical halogen-bonded organic framework (XOF). The radical monomer, benzimidazole triphenylmethyl (BTTM), was synthesized through the coupling of TTM radicals with benzimidazole.

2021年5月2日 · 进一步，作者利用同样的研究方法构建了一种新的二维卤键有机框架（xof-tppe）。作者通过 1 h nmr、uv-vis、xps、ir、sem、tem、hrtem和saed进行监测，证明了xof-tppe的形成，同时，通过粉末x射线衍射（pxrd）和理论模拟研究，进一步确立了xof-tppe的结构。

2024年6月7日 · In this work, we present the inaugural construction of stable bromine (I)-bridged two-dimensional (2D) halogen-bonded organic frameworks, XOF (Br)−TPy−BF4/OTf, based on sensitive [N⋅⋅⋅Br⋅⋅⋅N] + halogen bonds. The formation of XOF (Br)−TPy−BF4/OTf was monitored by 1 H NMR, XPS, IR, SEM, TEM, HR-TEM, SEAD.

2024年10月8日 · XOF-TNP enables the development of a novel rewritable security paper, utilizing its iodine adsorption properties to encrypt and decrypt QR codes. This research expands the application scope of halogen-bonded organic frameworks, providing insights into the design of materials for environmental remediation and security applications.

2023年7月2日 · The new-found XOF, namely TIEPE-DABCO, exhibits enhanced emission in the solid state and turn-off emission sensing of acid vapors and explosives like picric acid in nanomolar quantity.

2021年6月25日 · The structural model of XOF-TPPE was established based on powder X-ray diffraction (PXRD) data and theoretical simulations. Significantly, synchrotron small-angle X-ray scattering (SAXS), DLS and UV-Vis spectroscopy experiments suggested that XOF-TPPE still maintains a stable 2D framework structure in solutions.

2022年9月13日 · XOF-TPy and XOF-TPEB were characterized by 1 H NMR, UV–vis, X-ray photoelectron spectroscopy (XPS), IR, SEM, and HR-TEM. Two-dimensional (2D) structural models were established based on powder X-ray diffraction (PXRD) …

Herein, a novel two‐dimensional (2D) halogen‐bonded organic framework (XOF–TPPE) was successfully designed and fabricated by iodonium‐bridged N⋅⋅⋅I+⋅⋅⋅N interactions between pyridyl groups and I+ for the first time.

Extendable-output function (XOF) is an extension [1] of the cryptographic hash that allows its output to be arbitrarily long. In particular, the sponge construction makes any sponge hash a natural XOF: the squeeze operation can be repeated, and the regular hash functions with a fixed-size result are obtained from a sponge mechanism by stopping ...
