(Figure Presented) En route to bits and bytes: The integration of complex logic functions within individual molecules allows data processing at the molecular level, as demonstrated by recently reported molecular encoder and decoder devices. This research on decision-making molecules has great potential for future applications and more complex computing on a functional unimolecular platform. © 2010 Wiley-VCH Verlag GmbH & Co.

The heterogeneous catalytic performance is largely dependent on the catalyst nanostructures or, in another word, processing technologies, in addition to the intrinsic physical and chemical properties of the constitutive components. Compared to the amorphous framework of mesoporous silica, mesoporous metal oxides synthesized by a hard templatereplicating method usually have a crystallized structure and exhibit excellent catalytic activities, as reported in many documents. The loading or dispersion of catalytically active guest species into the host mesopore network results in mesostructured composites of a crystallized framework and highly dispersed catalytic species in its mesopore network. Mesoporous inorganic oxide materials, in the form of either powder or thin film, with high surface areas, ordered pore structures, finely tunable pore sizes, and flexible wallcompositions have been investigated widely of their chemical synthesis and potential applications in catalysis, adsorption, chemical sensing, electrochemistry, biomedical areas, and so on.

ConspectusAiming to construct various novel supramolecular polymeric structures in aqueous solution beyond small supramolecular self-assembly molecules and develop functional supramolecular polymeric materials, research interest on functional supramolecular polymers has been prevailing in recent years. Supramolecular polymers are formed by bridging monomers or components together via highly directional noncovalent interactions such as hydrogen bonding, hydrophobic interaction, π-π interaction, metal-ligand coordination, electrostatic interaction, and so forth. They can be easily functionalized by employing diverse building components with specific functions besides the traditional polymeric properties, a number of which are responsive to such external stimuli as pH variance, photoirradiation, chemically or electrochemically redox with the controllable conformation or construction switching, polymerization building and rebuilding, and function adjustment reversibly owing to the reversibility of noncovalent interactions. Supramolecular polymers are "soft matters" and can be functionalized with specific properties such as morphology adjustment, controllable luminescence, shape memory, self-healing, and so forth. Supramolecular polymers constructed based on macrocycle recognition and interlocked structures represent one typical branch of the supramolecular polymer family. Cyclodextrin (CD), cucurbituril (CB), and hydrophilic calixarene derivatives are usually employed to construct hydrophilic supramolecular polymers in aqueous solution. Stimuli-responsive hydrophilic supramolecular polymers, constructed in aqueous solution particularly, can be promising candidates for mimicking biocompatible or vital functional materials.This Account mainly focuses on the recent stimuli-responsive supramolecular polymers based on the host-guest interaction in aqueous solution. We describe the hydrophilic supramolecular polymers constructed via hydrophobic effects, electrostatic interaction, metal-ligand coordination, and multiple combinations of the above noncovalent interactions. The disparate ways to engender stimuli-responsive supramolecular polymers via the hydrophobic effects of α-CD, β-CD, and γ-CD macrocycles are illustrated and discussed. Some recent works on CD-based photoresponsive functional supramolecular polymers are summarized. CB (especially CB[8]) based supramolecular polymers and their pH-responsive and photoresponsive properties are introduced. Hydrophilic calixarene derivative (bis(p-sulfonatocalix[4]arene) typically) based supramolecular polymers via electrostatic interactions are reviewed, and their redox-responsive association/disassociation elaborated in detail. More complicate supramolecular polymers based on multiple noncovalent interactions are illustrated including hydrophobic effect, metal-ligand coordination, and electrostatic interactions and their functional stimuli-responsiveness elaborated as well. Finally, we give perspectives on the strength of these diverse noncovalent interactions to form supramolecular polymers in aqueous solution, on the advantage, disadvantage, efficiency, and reversibility of using certain stimuli in constructing supramolecular polymers and prospect the future function improvement of these polymers as functional materials. © 2014 American Chemical Society.

Hollow-structured mesoporous materials (HMMs), as a kind of mesoporous material with unique morphology, have been of great interest in the past decade because of the subtle combination of the hollow architecture with the mesoporous nanostructure. Benefitting from the merits of low density, large void space, large specific surface area, and, especially, the good biocompatibility, HMMs present promising application prospects in various fields, such as adsorption and storage, confined catalysis when catalytically active species are incorporated in the core and/or shell, controlled drug release, targeted drug delivery, and simultaneous diagnosis and therapy of cancers when the surface and/or core of the HMMs are functionalized with functional ligands and/or nanoparticles, and so on. In this review, recent progress in the design, synthesis, functionalization, and applications of hollow mesoporous materials are discussed. Two main synthetic strategies, soft-templating and hard-templating routes, are broadly sorted and described in detail. Progress in the main application aspects of HMMs, such as adsorption and storage, catalysis, and biomedicine, are also discussed in detail in this article, in terms of the unique features of the combined large void space in the core and the mesoporous network in the shell. Functionalization of the core and pore/outer surfaces with functional organic groups and/or nanoparticles, and their performance, are summarized in this article. Finally, an outlook of their prospects and challenges in terms of their controlled synthesis and scaled application is presented.

Diketopyrrolopyrrole (DPP) pigments have been widely used in inks, paints, and plastics since it was first developed back in the early 1970s. The DPP-based materials were gradually exploited by optical and electrical applications for the excellent fluorescent properties and good charge carrier mobility. In recent years, great interest has been focused on developing organic photovoltaic functional materials containing a DPP core and attractive efficiencies have been achieved. This feature article describes the application of DPP-based materials, highlighting the applications in optoelectrical fields. © The Royal Society of Chemistry 2012. Source
