A 20-Å-Thick Interwoven Sheet Consisting of Nanotubes Ok-Sang Jung Yun Ju Kim Kwan Mook Kim Young-A Lee 10.1021/ja026774s.s002 https://acs.figshare.com/articles/journal_contribution/A_20-_-Thick_Interwoven_Sheet_Consisting_of_Nanotubes/3644073 Slow diffusion of AgNO<sub>3</sub> with Me<sub>2</sub>Si(4-Py)<sub>2</sub> yields an interwoven 2-nm-thick sheet consisting of the building block [Ag<sub>3</sub>(Me<sub>2</sub>Si(4-Py)<sub>2</sub>)<sub>4</sub>](NO<sub>3</sub>)<sub>3</sub>·H<sub>2</sub>O. The interweaving induces unique nanotunnels with a 16 × 18 Å<sup>2</sup> cross section with a 7 × 8 Å<sup>2</sup> square pore. The anion NO<sub>3</sub><sup>-</sup> of the skeletal sheet can be reversibly exchanged with appropriately sized anions without the collapse of its structural integrity. The compound has a melting point (140 °C) and exists as the first 2D ionic liquid up to 193 °C. 2002-06-13 00:00:00 compound pore Ag 3 integrity building block collapse nanotunnel diffusion Nanotube reversibly Si anion AgNO 3 2 D yield section Thick
