“…Different studies seem to indicate that the most promising way to bond CDs in fabrics would be to generate complexes of monochlorotriazinyl-CDs by binding CDs with trichlorotriazines [ 104 ]. β-CDs can also be used as a novel molecular phosphorescent material as light sensitive phosphorescent color changes have been detected, which makes it a promising candidate as dynamically photo-functional material [ 105 ]. Other applications of CDs in fabrics and textiles can be seen in Table 6 .…”

Cyclodextrins (CDs) are cyclic oligomers broadly used in food manufacturing as food additives for different purposes, e.g., to improve sensorial qualities, shelf life, and sequestration of components. In this review, the latest advancements of their applications along with the characteristics of the uses of the different CDs (α, β, γ and their derivatives) were reviewed. Their beneficial effects can be achieved by mixing small amounts of CDs with the target material to be stabilized. Essentially, they have the capacity to form stable inclusion complexes with sensitive lipophilic nutrients and constituents of flavor and taste. Their toxicity has been also studied, showing that CDs are innocuous in oral administration. A review of the current legislation was also carried out, showing a general trend towards a wider acceptance of CDs as food additives. Suitable and cost-effective procedures for the manufacture of CDs have progressed, and nowadays it is possible to obtain realistic prices and used them in foods. Therefore, CDs have a promising future due to consumer demand for healthy and functional products.

“…2,3 Supramolecules, among the various smart materials, have been demonstrated as the most potential one because they can be designed at the molecular level depending on the requirements. 4 The supramolecule materials consisting of a multi-functional molecule monomer have the potential to modulate their structures and functionalities 5,6 upon external environmental changes such as pH, 7 temperature 8 and mechanical forces. 9 Supramolecule formation is commonly favoured by the selfassembly of its monomers based on the weak interactions such as p-p interaction 10 and hydrogen-bonding.…”

Herein, we present three imidazo[1,2-a]pyridin-2(3 H)-one derivatives that are diamagnetic in solution, but paramagnetic in the solid state, possibly owing to a stacking-induced formation of phenoxide-type radicals. Notably, a larger bathochromic shift of the absorption (even up to the near- infrared region) of these three compounds was observed in the solid state than in solution, which was attributable to the ordered columnar stacking arrangements or their single-electron character as radicals in the solid state. Interestingly, compared to that in solution, (E)-3-(pyridin-4'-ylmethylene)imidazo[1,2-a]pyridine 2(3 H)-one displayed a largely red-shifted emission (centered at 660 nm, with tailing above 800 nm) in the solid state. A larger bathochromic shift (260 nm) of the emission is an indication of better order and tight stacking in the solid state, which is brought about by the rigid and polar acceptor. These three compounds also reveal different magnetic susceptibilities at 300 K, thus implying that they possess various columnar stacking structures. Most interestingly, these three radicals exhibit unusual ferromagnetic-to-antiferromagnetic phase transitions, which can be attributed to anisotropic contraction and non-uniform slippage of the columnar stacking chains.
