Functional Supramolecular Nanoassemblies Of Conjugated Molecules

Π-conjugated systems of delocalized aromatic electrons along their backbones, including conjugated small molecules, oligomers, polymers, and carbonaceous materials, etc., have received considerable attention from a wide variety of scientific and technical communities. Compared to inorganic materials, the advantages of those based on π-tectons lie in their broad diversity, flexibility, and tunability with regard to structure/geometry/morphology, processability, composition, functionality, electronic/band structure, etc. In terms of sophisticated molecular engineering, these features endow them not only with excellent self-assembly properties but also with unique optical, electrical, mechanical, photophysical, photochemical, and biochemical attributes. This renders them promising scaffolds for advanced functional materials (AFMs) in numerous areas of general interest such as electronics, optics, optoelectronics, photovoltaics, magnetic and piezoelectric devices, sensors, catalysts, biomedicines, and others. With regard to the design/synthesis of novel π-tectons, the launch of diverse assembly/fabrication protocols, theoretical calculations, etc., the past several decades have witnessed tremendous advancements along this direction. Thus far, a vast array of high-performance π-tectons-based AFMs have been initiated. To some extent, the cooperative principle of π-πstacking and other noncovalent interactions has been revealed, and the structure-property relationships have been disclosed. Despite the existing progress, this field still faces challenges, for example: (i) the need for scalable assembly/manufacture under ambient conditions—with low-cost, facile, environmentally-friendly protocols (ii) clearer correlations bridging the underlying intricate relationships of each successive step in assembly/manufacture (iii) corresponding theoretical calculations for guiding the rational design of π-tectons that elucidate the cooperative principle of π-π stacking and other noncovalent interactions, as well as the principle of structure-performance correlation (iv) stability and durability, among the most important concerns regarding their commercialization The advancements accumulated during the past decades have established a solid foundation for the further development of π-conjugated systems-based AFMs. We believe that with unrelenting efforts from both scientific and technical communities of various backgrounds, their practical applications will eventually be fulfilled. This Research Topic aims to address the above-mentioned challenges

Explanation of the structure-property relationship of a given molecule is generally simple because the characteristics of the atomic groups and chemical bonds and the effects emerging from their interaction have long been known, both from theore- cal studies and numerous experimental results. In contrast, it is often difficult to analyze, estimate, and account for the structure-properties relationship in sup- molecules. The characteristics of supramolecules are governed both by the nature of the constituent molecules and by their configuration while the characteristics of the constituent molecules are usually evident as mentioned above; their configu- tions are difficult to control, predict, and accurately estimate because of insufficient knowledge regarding the intermolecular forces. Moreover, since most of the int- molecular forces constructing supramolecules are weak, the supramolecular str- ture may vary depending on various factors, such as modification of the molecular structure, auxiliaries, and experimental conditions. Thus, in order to obtain supramolecules with the desired structures and properties, theoretical investigations on the intermolecular forces and accumulation of experimental studies on the re- tionship between the supramolecular structure and properties are both important.
