Salicylaldehydate coordinated two-dimensional-conjugated metal-organic frameworks

A novel class of copper-based 2D-c-MOF was synthesized from 1,3,5-triformylphloroglucinol using green mechano-chemistry. Herein, metal coordination with the salicylaldehyde functional moiety was explored for the first time in MOFs. Moreover, an intrinsic semiconductive copper-based SA-MOF thin film was fabricated using an in situ salt-free method at room temperature. We have demonstrated a facile, scalable, and green synthetic route to produce a novel class of semiconductive 2D-c-MOFs (SA-MOFs). This novel MOF chemistry opens rich opportunities for the exploration of functionally diverse open frameworks.
