The development of organic frameworks with radical skeletons is desired. 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 ...
There are three main types of crystalline porous frameworks, including covalent organic frameworks (COFs), metal organic frameworks (MOFs), and hydrogen-bonded organic frameworks (HOFs), which are classified according to the types of bonding models2. COFs are formed by the connection of covalent ...
Organic room-temperature phosphorescence, a spin-forbidden radiative process, has emerged as an interesting but rare phenomenon with multiple potential applications in optoelectronic devices, biosensing and anticounterfeiting. Covalent organic frameworks

complex formation wasn’t obtained. This finding provides more support for the dependence of halogen bonding on atomic polarizability. Utilizing similar donor-acceptor frameworks, the authors demonstrated that halogen bonding strength in the liquid crystalline state is comparable to the hydrogen-bonded ...
Twoヾimensional (2D) organic crystals with regular morphology and good photon confinement are potentially suitable for a chip﹕cale planar photonics system. Herein, through the bottom埐爋cess, 2D halogen‐bonded DPEpe〧4DIB cocrystals were fabricated that exhibit an asymmetric optical waveguide ...
Herein, to address these critical gaps, a series of halogen-bonded cocrystals were designed by changing the type and density of halogen atoms on halogen bond donor, and using nitrogen Lewis bases to participate in the bonding of σ-hole bond, so as to deeply reveal and comprehend structure–...
Due to the fascinating structures and wide applications, porous materials with open frameworks have attracted more and more attentions. Herein, a novel twoヾimensional (2D) halogen‐bonded organic framework ( XOF㏕PPE ) was successfully designed and fabricated by iodonium‐bridged N···I + ...
(6). Moreover, the activation energies for the halogen bonded complexes were found to be significantly lower than those of the hydrogen bonded complexes, with1having an activation energy of nearly half that of5, for example. Halide salt7, which has a water molecule in proximity of the ...
For example, density functional theory (DFT) and natural population analyses (NPAs) of ruthenium and organic dyes have shown that regeneration is preceded by formation of an ionic dye+-iodide pair5,6. A hypsochromic shift of the metal-to-ligand charge transfer (MLCT) band, changes in ligand...
