“…On the other hand, the material selection requires a clear understanding of the functional requirements for each component and various essential criteria considerations. Therefore, some researchers conducted a study of optimal [15] and straightforward methods for material selection [16][17][18][19][20]. However, these studies have not involved a relationship between material selection and the assembly process.…”

Complexity principles are very important for reducing difficulty while at the same time continuously attaining the requirements of the product, process, and system. A crucial factor affecting the complexity of assembly is material selection. The material used for a product will be closely linked to the handling and insertion process. In a previous study, the methods used to select materials and assembly processes have been developed separately. In this study, those methods will be developed together into a single entity with respect to the complexity of each process. Scientific information about this matter has yet to be revealed, so it still requires intensive study. Hence, the study aims to promote a new way to measure the complexity of parts assembly by examining the material selection parameters. The proposed method involves material coefficients in establishing an assembly complexity index and consists of two phases. Numerical examples are provided to illustrate the suggested design comprehensively, which uses three material variants in piston products to calculate the complexity index of the assembly process. Variants with a small complexity index are ideal and facilitate the assembly process. The study creates a material coefficient model to specify the assembly process, where each component has various coefficient values. The material coefficient describes the value of material characteristics related to the assembly method, namely the process of handling and insertion. The material selection requires a clear understanding of the assembly requirements for each component. The related material characteristics are density, fracture toughness, Young’s modulus, elastic limit, tensile strength, elongation, and hardness. Assessment of the complexity index using methods from previous studies obtained 6.02. Using the present method, 5.777 were obtained for variant 1 and 5.769 for the second variant. The mean complexity value is compatible with the material coefficient and assembly time

“…Among these nano-structures, metal-organic cages based on coordination-driven self-assembly have received a lot of attention from scientists in the past three decades due to the highly predictable nature of coordination bonds and the precise designability of the organic ligand. [23][24][25][26][27][28] Benefiting from their well-designed inner cavities, such metallo-cages have found useful applications in chemical sensing, [29][30][31] catalysis, [32][33][34][35] drug delivery [36][37][38] and host-guest chemistry. [39][40][41][42] Because of these advanced functional applications, chemists are paying much attention to the construction of supramolecular cages with unique three-dimensional structures.…”

“…Over the past few decades, supramolecular assembly has received increasing attention − due to its powerful method for the construction of diverse metal-containing entities with designed geometries and symmetries. − The methods of supramolecular assembly that have been reported and thus far mainly include coordination-driven self-assembly, , folding assembly, and templated methods (covalent scaffolds, metal-ion templates, , anionic templates, , etc.). However, these methods are primarily suitable for constructing supramolecular cages with high symmetry. , For the construction of twisted supramolecular cages, these methods are often less suitable due to the requirement for multiple driving forces to work synergistically.…”

“Cage Walking” Synthetic Strategy for Unusual Unsymmetrical Supramolecular Cages

Developing novel assembly methods for supramolecular compounds has long been a research challenge. Herein, we describe how to integrate the B–C coupling reaction and “cage walking” process into coordination self-assembly to construct supramolecular cages. In this strategy, dipyridine linkers containing alkynes react with the metallized carborane backbone through B–C coupling and then “cage walking” resulting in metallacages. However, dipyridine linkers without alkynyl groups can form only metallacycles. We can regulate the size of metallacages based on the length of the alkynyl bipyridine linkers. When tridentate-pyridine linkers participate in this reaction, a new type of ravel is formed. The metallization of carboranes, the B–C coupling reaction, and especially the “cage walking” process of carborane cages play a vital role in this reaction. This work provides a promising principle for the synthesis of metallacages and opens up a novel opportunity in the supramolecular field.
