The interesting physical and chemical properties of carbon nanotubes (CNTs) have prompted the search for diverse inorganic nanotubes with different compositions to expand the number of available nanotechnology applications. Among these materials, crystalline inorganic nanotubes with well-defined structures and uniform sizes are suitable for understanding structure–activity relationships. However, their preparation comes with large synthetic challenges owing to their inherent complexity. Herein, we report the example of a crystalline nanotube array based on a supertetrahedral chalcogenide cluster, K3[K(Cu2Ge3Se9)(H2O)] (1). To the best of our knowledge, this nanotube array possesses the largest diameter of crystalline inorganic nanotubes reported to date and exhibits an excellent structure-dependent electric conductivity and an oriented photoconductive behavior. This work represents a significant breakthrough both in terms of the structure of cluster-based metal chalcogenides and in the conductivity of crystalline nanotube arrays (i.e., an enhancement of ~4 orders of magnitude).

Recently, as a new class of proton-conductive materials, MOMs, also known as coordination polymers (CPs) and/or porous coordination polymers (PCPs), have attracted much interest due to their structural designability and uniform porosity. [15][16][17] MOMs are infinite coordination networks of metal ions bridged through organic ligands. Through judicious choices of structural components, the structural and physical properties of MOMs can be fine-tuned. [18,19] More importantly, thanks to the crystalline nature of MOMs, it is feasible to visualize the proton transportation pathways inside MOMs. [20] Furthermore, these advantages of MOMs enable

The interesting physical and chemical properties of carbon nanotubes (CNTs) have prompted the search for diverse inorganic nanotubes with different compositions to expand the number of available nanotechnology applications. Among these materials, novel crystalline inorganic nanotubes with well-defined structures and uniform sizes are extremely suitable for understanding structure–activity relationships. However, their preparation comes with large synthetic challenges owing to their inherent complexity. Herein, we report the first example of a crystalline nanotube array based on a supertetrahedral chalcogenide cluster, K3[K(Cu2Ge3Se9)(H2O)] (1). To the best of our knowledge, this nanotube array possesses the largest diameter of crystalline inorganic nanotubes reported to date and exhibits an excellent structure-dependent electric conductivity and an oriented photoconductive behavior. This work represents a significant breakthrough both in terms of the structure of cluster-based metal chalcogenides and in the conductivity of crystalline nanotube arrays (i.e. an enhancement of ~ 4 orders of magnitude).
