Hydrogen-bonded organic frameworks: design, structures and potential applications

03-Jul-2018 | Jie Luo; Jia-Wei Wang; Ji-Hong Zhang; Shan Lai; Di-Chang Zhong, CrystEngComm, 2018

Hydrogen-bonded organic frameworks (HOFs), a new type of porous material following the metal-organic frameworks (MOFs), covalent organic frameworks (COFs), etc., have emerged as one of the promising candidates in diverse potential applications. In this highlight, we summarize the key progress of ...

A well-grown [small beta]-Ga2O3 microrods array transformed by GaOOH on Si (100) substrate and growth mechanism study

03-Jul-2018 | Junhua Zhang; Shujie Jiao; Yongbiao Wan; Shiyong Gao; Dongbo Wang; Jinzhong Wang, CrystEngComm, 2018

Simple two step hydrothermal methods are introduced to succefully fabricate the well-grown β-Ga2O3 microrods array converted by GaOOH on Si (100) substrate without other heterogeneous layers, which overcome the relatively large surface energy. Different hydrothermal conditions are designed to ...

Electronic and reactivity characteristics of CL-20 covalent chains and networks: A density functional theory study

03-Jul-2018 | Margarita Aleksandrovna Gimaldinova; Mikhail Mikhailovich Maslov; Konstantin Petrovich Katin, CrystEngComm, 2018

The covalent low-dimensional nanostructures built with CL-20 units by means of CH2 molecular bridges are examined in order to investigate the possibility and probability of creating covalently bonded arrays with CL-20 fragments as building blocks. In this way, various CL-20 oligomers were ...

Iron(II) and cobalt(II) complexes based on anionic phenanthroline-imidazolate ligands: reversible single-crystal-to-single-crystal transformations

03-Jul-2018 | Alexandre Abhervé; Samia Benmansour; Carlos J. Gomez Garcia; Narcis Avarvari, CrystEngComm, 2018

A series of low-spin FeII and CoII complexes based on phenanthroline-imidazolate (PIMP) ligands is reported. The FeII complex (H9O4)[Fe(PIMP)3]·(C4H10O)2(H2O) (1a) shows reversible crystalline phase transformations to afford two new phases (H9O4)[Fe(PIMP)3]·(H2O) (1b) and ...

Nitramino-functionalized tetracyclic oxadiazoles as Energetic Materials with High performance and High Stability: Crystal Structures and Energetic Properties

03-Jul-2018 | Qi Sun; Ming Lu; Qiuhan Lin, CrystEngComm, 2018

A series of tetracyclic energetic materials are developed through the introduction of 1,2,4-oxadiazole into nitramino-1,2,5-oxadiazole. All these thirteen new compounds were fully characterized and seven of them were further confirmed by single crystal X-ray diffraction. Salt formation leads to ...

A Rough Guide to Molecular Solid Solution: Design, Synthesis and Characterization of Mixed Crystals.

03-Jul-2018 | matteo lusi, CrystEngComm, 2018

Crystalline solid solutions are a long known class of materials that enables the fine tuning of a material structure and properties. Some of them like metal alloys have been employed in everyday life for thousands of years. As result, these phases represent an important part of materials science. ...

Insights on the interaction of calcein with calcium carbonate and its implications in biomineralization studies

03-Jul-2018 | Giulia Magnabosco; Iryna Polishchuk; Simona Fermani; Jonathan Erez; Boaz Pokroy; Giuseppe Falini, CrystEngComm, 2018

The effects of calcein, a fluorescent marker commonly used to assess mineral growth in calcifying organism, on calcite and aragonite structure have been investigated. Calcein is entrapped within calcite and aragonite and modifies the shape and morphology of both polymorphs. Moreover, in the ...
