“…[25] Using transmission electron microscopy (TEM), the authors proposed a mode of self-assembly analogous to wormlike inverted micelles. They suggested that the carbohydrate units were located in the centre of the fibres, with the steroid groups surrounding the carbohydrate core.…”

In the past 10 years, the molecular self-assembly and network formation of small molecule gelators has become one of the most active frontiers of the emergent area of nanochemistry. Increasingly, research efforts have begun to focus on multicomponent gelators, which rely on the initial interaction of distinct individual components to form a complex that subsequently self-assembles into a fibrous supramolecular polymer. In true two-component systems, an individual component can be present in isotropic solution, and only on addition of the second component will a gel actually form. In some cases, however, two-component gels are reported in which the second component significantly modifies the behaviour of a known gelator. Both systems are discussed in this article. The additional level of supramolecular control in the hierarchical self-assembly of two-component gels confers exquisite tunability and controllability. Functionality can be readily built into the material by simple variation of one of the individual components. This article discusses the key approaches used to control self-assembly by manipulating single molecular-recognition events and illustrates how controlling the transcription of information from the molecular to the macroscopic level by the simple addition of a second component allows complex functional materials to be selectively assembled from simple building blocks.

Abstract:The synthetic method for preparing N-(3-hydroxypropyl) 3α,12α-dihydroxy-5β-cholan-24-amide can lead to formation of at least three different crystal forms -an anhydrous compound and two monohydrates. The structural and thermal properties of these forms have been characterized by 13 C-CP/MAS-NMR and IR spectroscopy, thermogravimetry, differential scanning calorimetry and by powder and single crystal x-ray crystallography. In addition, theoretical 13 C-NMR chemical shift calculations were also performed for the anhydrous compound and for the first monohydrate, starting from single crystal structures and the structures of these species have now been verified. The first monohydrate, C 27 H 47 NO 4 · H 2 O, crystallizes in orthorhombic space group P2 1 2 1 2 1 with cell parameters: a = 7.1148(2), b = 18.1775(5), c = 20.1813(6), Z = 4.
