| dc.description.abstract | The optimum solvent for Nb2Se9 dispersion, which is a new type of one dimensional (1D) material, is investigated. Among several solvents (16 solvents in total), strong dispersion was observed in benzyl alcohol, isopropyl alcohol, isobutyl alcohol, and diacetone alcohol, which have medium dielectric constants in the range of 10 to 30 and surface tension in the range of 25 to 35 mJ m−2 . 1D Nb2Se9 chains, whose size is less than 10 nm, are well dispersed and it is possible to disperse mono-chains of 1 nm or less in a specific dispersion region. The 1D unit chain with dangling bond free surface and high volume to area ratio is expected to be used in applications that utilize the surface of the material. Such dispersion is an important first step towards various potential applications and is an indispensable scientific goal for the practical applications of Nb2Se9 . | - |

| dc.description.sponsorship | In summary, a novel 1D inorganic molecular chain material (Nb22Se99) was synthesized through chemical reaction between Nb and Se; 1D nano-sized (≤10 nm) Nb2Se9 molecular chains were chemical reaction between Nb and Se; 1D nano-sized (≤10 nm) Nb2Se9 molecular chains were successfully obtained by dispersion. Of the various solvents tested (total 16 solvents), strong dispersions successfully obtained by dispersion. Of the various solvents tested (total 16 solvents), strong were obtained with green solvents such as benzyl alcohol, isopropyl alcohol, isobutyl alcohol, dispersions were obtained with green solvents such as benzyl alcohol, isopropyl alcohol, isobutyl and diacetone alcohol, whose dielectric constant was in the range of 10 to 30 and surface tension was in alcohol, and diacetone alco−1hol, whose dielectric constant was in the range of 10 to 30 and surface the range of 25 to 35 mJ m . The best results−1 were obtained in a diacetone alcohol with a concentration tension was in th−e 1range of 25 to 35 mJ m . The best results were obtained in a diacetone alcohol with of 85.83 µg mL . It can be enhanced−1 through the additional design of solvent combination and a concentration of 85.83 µg mL . It can be enhanced through the additional design of solvent dispersant. These results can provide the essential information of the material’s surface for design of combination and dispersant. These results can provide the essential information of the material’s the further exfoliation strategy, and can be recognized as an important step towards various potential surface for design of the further exfoliation strategy, and can be recognized as an important step applications of 1D Nb2Se9, such as transistors, sensors, composites, and solar cells. towards various potential applications of 1D Nb2Se9, such as transistors, sensors, composites, and solar cells.
