Specifications | MSDS | Literature and Reviews


2,4,6-Tris(4-ethynylphenyl)-1,3,5-triazine (TEPT), CAS number 425629-22-7, featuring a nitrogen rich electron deficient triazine core with three 4-ethynylphenyl side arms. The ethynyl functional groups extend the structure by forming covalent organic frameworks (COFs) via Sonogashira–Hagihara cross-coupling reaction, or by click polymerisation reaction with azides to form microporous organic polymers.

Obtained from 2,4,6-tris(4-ethynylphenyl)-1,3,5-triazine unit and aromatic azide linkers by click polymerization reaction, microporous organic polymer CMOP-1 exhibited a Brunauer–Emmett–Teller (BET) surface area of 431 m2·g−1 and a narrow pore size distribution under 1.2 nm. CMOP-1 demonstrated a superior CO2 uptake level of 1.85 mmol·g−1 at 273 K/1.0 bar, H2 uptake of up to 2.94 mmol·g−1 at 77 K/1.0 bar, and I2 vapor adsorption load of 160 wt.%, owing to the rich nitrogen content.
