TI  - New Layered Triazine Framework/Exfoliated 2D Polymer with Superior Sodium-Storage 
      Properties.
LID - 10.1002/adma.201705401 [doi]
AB  - The efficient synthesis of 2D polymers (2DPs) with tailorable structures and 
      properties is highly desired but remains a considerable challenge. Here, the 
      first solution synthesis of millimeter-size crystalline covalent triazine 
      frameworks (CTFs) with a clear lamellar structure, which can be exfoliated into 
      micrometer-size few-layer 2DP sheets via both micromechanical cleavage and liquid 
      sonication, is reported. The obtained CTFs or 2DPs show a unique staggered AB 
      stacking with a dominant pore size of  approximately 0.6 nm, which is different from the common 
      eclipsed AA stacking in various covalent organic frameworks. The preference for 
      AB stacking is due to the specific interaction of triflic acid with CTFs as 
      revealed computationally. When explored as new polymeric anodes for sodium-ion 
      batteries, both crystalline bulk CTF and exfoliated 2DP exhibit very high 
      capacities (225 and 262 mA h g(-1) at 0.1 A g(-1) , respectively), impressive 
      rate capabilities (67 and 119 mA h g(-1) at 5.0 A g(-1) , respectively), and 
      excellent cycling stability (95% capacity retention after 1200 cycles) due to 
      their robust conjugated porous structure, outperforming most organic/polymeric 
      sodium-ion battery anodes ever reported.
