“…Subsequently, UCLA opened a dedicated research centre, Functional Engineered Nano Architectonics, in 2003. In the same year, Stefan Hecht of the Freie Universität Berlin, Germany, published a paper titled 'Welding, Organizing, and Planting Organic Molecules on Substrate Surfaces -Promising Approaches towards Nanoarchitectonics from the Bottom Up' [61], which is the first paper to mention explicitly the term nanoarchitectonics in the title of an academic paper published in an international scientific journal. Three years prior to those events in 2000, Masakazu Aono had organized the first International Symposium on Nanoarchitectonics Using Suprainteractions in Tsukuba, Japan [62].…”

The development of science and technology of advanced materials using nanoscale units can be conducted by a novel concept involving combination of nanotechnology methodology with various research disciplines, especially supramolecular chemistry. The novel concept is called 'nanoarchitectonics' where self-assembly processes are crucial in many cases involving a wide range of component materials. This review of self-assembly processes reexamines recent progress in materials nanoarchitectonics. It is composed of three main sections: (1) the first short section describes typical examples of self-assembly research to outline the matters discussed in this review; (2) the second section summarizes self-assemblies at interfaces from general viewpoints; and (3) the final section is focused on self-assembly processes at interfaces. The examples presented demonstrate the strikingly wide range of possibilities and future potential of self-assembly processes and their important contribution to materials nanoarchitectonics. The research examples described in this review cover variously structured objects including molecular machines, molecular receptors, molecular pliers, molecular rotors, nanoparticles, nanosheets, nanotubes, nanowires, nanoflakes, nanocubes, nanodisks, nanoring, block copolymers, hyperbranched polymers, supramolecular polymers, supramolecular gels, liquid crystals, Langmuir monolayers, Langmuir-Blodgett films, self-assembled monolayers, thin films, layer-by-layer structures, breath figure motif structures, two-dimensional molecular patterns, fullerene crystals, metal-organic frameworks, coordination polymers, coordination capsules, porous carbon spheres, mesoporous materials, polynuclear catalysts, DNA origamis, transmembrane channels, peptide conjugates, and vesicles, as well as functional materials for sensing, surface-enhanced Raman spectroscopy, photovoltaics, charge transport, excitation energy transfer, lightharvesting, photocatalysts, field effect transistors, logic gates, organic semiconductors, thin-film-based devices, drug delivery, cell culture, supramolecular differentiation, molecular recognition, molecular tuning, and hand-operating (hand-operated) nanotechnology.

“…The term was also almost concurrently coined in 2001 in the name of a new Research Center for Interfacial Nanoarchitectonics led by Shimizu at the National Institute of Advanced Industrial Science and Technology in Japan. In addition, this terminology was first used in the title of a research paper by Hecht . Nanoarchitectonics is the basic concept of dynamically forming functional materials by harmonization of various factors including atomic‐/molecular‐level manipulation and control, chemical nanofabrication, self‐organization, and field‐controlled organization.…”

Nanoarchitectonics for Dynamic Functional Materials from Atomic‐/Molecular‐Level Manipulation to Macroscopic Action

mechanisms operate with excellent fl exibility/adaptability originating from cooperation of multiple dynamic systems. [ 1 ] In most cases, the functional components of these systems are assembled through non-covalent dynamic interactions. Although their assembled structures are often ambiguous, or "fuzzy," functions of biological systems are signifi cantly superior to any of the so far precisely constructed artifi cial machines and devices. Thus, fabrication of bio-like systems might be one of the ultimate goals of the science and technology of functional materials. There has already been some success in the synthesis of excellent new materials, [ 2 ] but these are still far inferior to biological materials systems from the point-of-view of specifi city, effi ciency, and adaptability, although incremental progress involving existing technological concepts may not change this situation. A certain paradigm shift in construction concepts of functional materials is necessary to establish an advanced approach towards truly dynamic functions.Fabrication of functional materials requires control of organization of their components with nanometer precision. The novel technological concept of nanotechnology has been established over the past few decades with a view to exploit nanometer-sized phenomena and to fabricate functional materials by precisely controlling the materials' structures at the nanoscale. [ 3 ] Several strategies of nanotechnology are simple extensions of the corresponding successful microtechnologies to nanofabrication. However, the control of nanoscale events and structures requires different approaches to those commonly applied in microtechnology. This is because physical phenomena at the nanoscale are quite different from microscopic phenomena. Effects occurring at the microscopic level are often similar to those occurring in the macroscopic regime. In contrast, nanoscale phenomena involving nanometer-sized objects are strongly infl uenced by thermal/statistical fl uctuations, mutual interactions, and possibly quantum effects between components. In many cases, such mutual actions are dynamically integrated, often resulting in unexpected properties and effects so that components of nanoscale systems cannot be controlled by intuitive means. To understand and therefore control nanoscale phenomena and to Objects in all dimensions are subject to translational dynamism and dynamic mutual interactions, and the ability to exert control over these events is one of the keys to the synthesis of functional materials. For the development of materials with truly dynamic functionalities, a paradigm shift from "nanotechnology" to "nanoarchitectonics" is proposed, with the aim of design and preparation of functional materials through dynamic harmonization of atomic-/molecular-level manipulation and control, chemical nanofabrication, self-organization, and fi eld-controlled organization. Here, various examples of dynamic functional materials are presented from the atom/molecularlevel to macroscopic dimensions. Thes...

Nanoarchitectonics beyond Self‐Assembly: Challenges to Create Bio‐Like Hierarchic Organization

Incorporation of non‐equilibrium actions in the sequence of self‐assembly processes would be an effective means to establish bio‐like high functionality hierarchical assemblies. As a novel methodology beyond self‐assembly, nanoarchitectonics, which has as its aim the fabrication of functional materials systems from nanoscopic units through the methodological fusion of nanotechnology with other scientific disciplines including organic synthesis, supramolecular chemistry, microfabrication, and bio‐process, has been applied to this strategy. The application of non‐equilibrium factors to conventional self‐assembly processes is discussed on the basis of examples of directed assembly, Langmuir–Blodgett assembly, and layer‐by‐layer assembly. In particular, examples of the fabrication of hierarchical functional structures using bio‐active components such as proteins or by the combination of bio‐components and two‐dimensional nanomaterials, are described. Methodologies described in this review article highlight possible approaches using the nanoarchitectonics concept beyond self‐assembly for creation of bio‐like higher functionalities and hierarchical structural organization.
