Modularity in Organic Solid State and Supramolecular Chemistry

Connection between the concept of modularity and how it relates to both organic solid state and supramolecular chemistry is discussed. It is demonstrated how the interrelationship between the three areas can be exploited to control chemical reactivity in the solid state. Specifically, it is shown how these areas can be used to achieve and fine-tune reactivity in organic solids. How modularity relates to other chemical systems, as well as to other areas of technology, is also discussed

Queer Youth and the Culture Wars: From Classroom to Courtroom in Australia, Canada and the United States

This article builds on Lugg\u27s (2006) discussion of surveillance in public schools and how queer youth are resisting schools\u27 current efforts to regulate sexual orientation and gender expression in the U.S. and internationally. Legal complaints initiated by queer youth against their schools for harassment and access to extra-curricular activities are discussed. The number of cases in the past five years has increased significantly and the courts are siding with the youth and their allies, demonstrating that queer youth are significantly impacting the dismantling of heteronormative regulatory regimes and improving the school experiences for themselves and queer adults

An Inverted Metal-Organic Framework with Compartmentalized Cavities Constructed by Using an Organic Bridging Unit Derived from the Solid State

Gridlock: A porous metal–organic framework with an interior tailored supramolecularly with organic groups is described (see structure; two grids have been differentiated using cyan and gray, while the yellow spheres represent included methyl groups). The approach relies on inverting the role of a secondary building unit (SBU) and an organic linker such that the organic linker serves as a node and the SBU serves as a linear bridge. The organic node used to construct the framework has been obtained by way of a template‐directed solid‐state organic synthesis

Discrete versus Infinite Molecular Self-Assembly:0.167em Control in Crystalline Hydrogen-Bonded Assemblies Based on Resorcinol

[GRAPHICS] Cocrystallization of 1,2-bis(4-pyridyl)ethane (4,4’-bipyeth) with resorcinol (res), 4-chlororesorcinol (4-Cl-res), and 4,6-dichlororesorcinol (4,6di-Cl-res) yields molecular solids (4,4’-bipyeth). (res) la, 2(4,4’-bipyeth).2(4-Cl-res) 1b, and 2(4,4’-bipyeth).2(4,6-di-Cl-res) is with components held together by 0-H . . .N hydrogen bonds. In 1a the components form an infinite 1D polar array, whereas in 1b and is the components form OD four-component complexes. Formation of the discrete assemblies is attributed to peripheral steric effects, which block the solid-state polymerization

Inverted metal–organic frameworks: solid-state hosts with modular functionality

Metal-organic frameworks (MOFs) are crystalline inorganic-organic hybrid materials that consist of metal ions and organic molecules connected in space to produce an infinite one-, two-, or three-dimensional framework. The modularity of MOFs, specifically, the ability to modify the organic and/or inorganic components, offers a ready means to modify and control properties of such materials (e.g. inclusion, magnetism). This review highlights the design and synthesis of cavity-containing and porous MOFs with emphasis on methods that enable the functionalization of interior void spaces with organic groups. A relatively new class of MOFs, known as inverted metal-organic frameworks (IMOFs), which enables organic functionalization using principles of supramolecular chemistry, is discussed. We also briefly outline methods to functionalize the interior spaces of mesoporous materials (MCMs) and zeolites, and suggest that MOB offer a diverse space within which to place a wide range of organic functionalities.
