“…39 As a forefront observation and analysis technique, Harano and Nakamura very recently developed a technique (single-molecule atomic-resolution real-time electron microscope, SMART-EM) to enable the recording of in situ video imaging of a single fullerene molecule with shuttling and rotating motions. 40 This advanced analytical method is supported by entrapment of fullerene molecules in the nanospaces of carbon nanotubes (Fig. 2).…”

For materials development with high-level structural regulations, the emerging concept of nanoarchitectonics has been proposed. Analytical sciences, including sensing/detection, sensors, and related device construction, are active targets of the nanoarchitectonics approach. This review article focuses on the two features of interface and nanostructures are especially focused to discuss nanoarchitectonics for analytical science. Especially, two selected topics, (i) analyses on molecular sensing at interfaces and (ii) sensors using self-assembled supramolecular nanostructures, are exemplified in this review article. In addition to recent general examples, specific molecular recognition at the air-water interface and fabrication of sensing materials upon self-assembly of fullerene units are discussed. Descriptions of these examples indicate that nanoarchitectonics and analytical science share common benefits, and therefore, developments in both research fields should lead to synergies.

“…[ 48 ] Recently, they demonstrated the real‐time video imaging of fullerene molecules, trapped within the nanospaces of carbon nanotubes, with extremely small standard errors of 0.9 ms in time and 0.01 nm in space (Figure 2C). [ 49 ] This remarkable nanotechnological development enables us to observe in situ molecular motions within nanospaces with a recording rate of 1600 frames per second. In addition, the related advanced technology was used for the atomic‐level analyses of the initial nanoporous material formation steps.…”

discovery of materials and principles. However, the mechanisms underpinning high-performance material synthesis are inordinately complex, much beyond our expectations, owing to the requirement of a large number of necessity factors. The trial-and-error approaches and/or strategies based on human intuition and experience with conventional synthesis methodologies may never end. Overall, it is never completely clear whether we are on the right path toward the development of materials exhibiting unparalleled performance in various applications.For example, porous materials with nanospaces, such as, zeolites, activated carbons, and silica gels, are expected to be widely applicable in various fields such as environment, energy, optics, electronics, and biomedicine. [5] The increasing demand for sustainable energy and environmental remediation has accelerated the research on various technologies related to energy storage and conversion, for example, fuel cells, [6] water splitting, [7] and rechargeable batteries. [8] These technologies heavily rely on catalyst and electrode materials, [9] which can significantly increase the efficiency of the involved chemical reactions by reducing their activation energy or by modulating the reaction mechanism. [10] Nanoporous materials, [11] owing to their unique features such as high surface areas, large pore volumes, and high adsorption capability, [12] are considered as potential candidates for such catalysts and catalyst supports.Zeolite and other conventional nanoporous materials have been researched for several decades. [13] Mesoporous materials Materials science and chemistry have played a central and significant role in advancing society. With the shift toward sustainable living, it is anticipated that the development of functional materials will continue to be vital for sustaining life on our planet. In the recent decades, rapid progress has been made in materials science and chemistry owing to the advances in experimental, analytical, and computational methods, thereby producing several novel and useful materials. However, most problems in material development are highly complex. Here, the best strategy for the development of functional materials via the implementation of three key concepts is discussed: nanotechnology as a game changer, nanoarchitectonics as an integrator, and materials informatics as a super-accelerator. Discussions from conceptual viewpoints and example recent developments, chiefly focused on nanoporous materials, are presented. It is anticipated that coupling these three strategies together will open advanced routes for the swift design and exploratory search of functional materials truly useful for solving real-world problems. These novel strategies will result in the evolution of nanoporous functional materials.

“…For example, a method for mechanical motions real‐time imaging for of a single molecular shuttle was realized in millisecond precision with sub‐angstrom resolution, as reported by Harano and co‐workers. [ 66 ] Molecular mechanical motions under quantum controls with unavoidable fluctuations from environments are not well visualized although this is crucially important matter in basic science. Video imaging of a single fullerene molecule within a carbon nanotube at various motional modes such as shuttling and rotating in interaction with carbon nanotube wall was demonstrated using an electron microscope equipped with a fast camera and denoising algorithm.…”

Mechanical stimuli have rather ambiguous and less‐specific features among various physical stimuli, but most materials exhibit a certain level of responses upon mechanical inputs. Unexplored sciences remain in mechanical responding systems as one of the frontiers of materials science. Nanoarchitectonics approaches for mechanically responding materials are discussed as mechano‐nanoarchitectonics in this review article. Recent approaches on molecular and materials systems with mechanical response capabilities are first exemplified with two viewpoints: i) mechanical control of supramolecular assemblies and materials and ii) mechanical control and evaluation of atom/molecular level structures. In the following sections, special attentions on interfacial environments for mechano‐nanoarchitectonics are emphasized. The section entitled iii) Mechanical Control of Molecular System at Dynamic Interface describes coupling of macroscopic mechanical forces and molecular‐level phenomena. Delicate mechanical forces can be applied to functional molecules embedded at the air–water interface where operation of molecular machines and tuning of molecular receptors upon macroscopic mechanical actions are discussed. Finally, the important role of the interfacial media are further extended to the control of living cells as described in the section entitled iv) Mechanical Control of Biosystems. Pioneering approaches on cell fate regulations at liquid–liquid interfaces are discussed in addition to well‐known mechanobiology.
