Engineering molecular crystals with abnormally weak cohesion.
نویسندگان
چکیده
Adding astutely placed methyl groups to hexaphenylbenzene increases molecular weight but simultaneously weakens key C-H···π interactions, thereby leading to decreased enthalpies of sublimation and showing that materials with abnormally weak cohesion can be made by identifying and then obstructing interactions that help control association.

Crystals of cage-like molecules: A van der Waals density functional study
A recently developed ab initio van der Waals density functional (vdWDF) [1] includes long-range dispersion forces at an electronic level. It promises to extend large-scale electronic structure calculations to the realm of soft and sparse matter. Consequently, it has spurred many studies on supramolecular systems including molecular dimers, physisorption systems, and polymer bundles [2]. We inve...
متن کاملNano-sized AlPO4-5 Crystals: Synthesis and characterization
Molecular sieves and zeolites are materials whose crystalline frameworks form nanometer or subnanometer pores. A variety of different crystal structures are known having a range of pore sizes. Because the pore sizes are usually smaller than 2 nm, they are classified as microporous materials. Synthesis of microporous materials is usually conducted by the high temperature treatment (80-200 °C) of...

متن کاملDetection of Polymer Brushes developed via Single Crystal Growth
Single crystals consisting various surface morphologies and epitaxial structures were applied to investigate the effect of other phase regions in the vicinity of a given tethered chains-covered area having a certain molecular weight of amorphous brushes. The designed experiments demonstrated that regardless of the type of surface morphology (patterned and especial mixed-brushes, homo and co...
متن کاملتحلیل ریز ساختی بلورهای کوارتز در آندالوزیت-کردیریت شیست با استفاده از پراش پراکندگی الکترونی
The present study investigates the shape preferred orientation (SPO) and crystal preferred orientation (CPO) of quartz crystals using electron backscatter diffraction (EBSD) in andalusite-cordierite schist from the Ythan Valley, Aberdeenshire, in the Scottish Dalradian block. Quartz crystals in the matrix and andalusite pophyroblasts have inequant to slightly equant shapes. Quartz crystals show...
