| Abstract: | We report the synthesis of HKUST‐1 (Cu3(btc)2; btc=benzene‐1,3,5‐tricarboxylate) and its growth kinetics by dynamic light scattering completely at room temperature without prior nucleation‐induction steps. Upon an increase in concentration of the starting solutions, the generation of a pure phase requires adjustment of the H2O/EtOH ratio. The presence of DMF is important to avoid competitive side phases. Replacement of DMF by a minimal amount of diethylamine resulted in the instantaneous formation of pure HKUST‐1 upon mixing at room temperature. Additionally, the synthesis parameters strongly influence the final crystallite size and porous properties. |
