Fluorescent Zn-based hetero-MOFs design via single metal site substitution

Two pairs of novel Zn-based MOFs with the same structures are synthesized. The exchange mechanism between the primary MOFs and the substituted MOFs is discussed. The utilization of the single metal site substitution in pre-formed Zn-based MOFs appears suited to the design of isostructural Zn-based hetero-MOFs with different photoluminescence properties.
