Adenosine 5'-monophosphate (AMP) has been used as a ligand to coordinate with Sn(iv) to synthesize porous coordination polymers (Sn-AMPs), which exhibited superior catalytic ability in converting biomass-derived sugars to 5-hydroxymethylfurfural (HMF). Protonated N1 and OH-P of coordinated AMP can form hydrogen bonds with glucose and fructose, enhancing the conversion of sugars.
Adenosine 5 '-monophosphate (AMP) with multiple functional groups can bind to various metal ions. In this work, AMP has been used as a ligand to coordinate Sn(iv) for the synthesis of porous coordination polymers (Sn-AMPs). The Sn-AMPs have both Bronsted acid (BA) and Lewis acid (LA) sites and have been used as bifunctional heterogeneous catalysts for catalyzing the conversion of sucrose to 5-hydroxymethylfurfural (HMF), involving hydrolysis of sucrose to glucose and fructose, isomerization of glucose to fructose, and dehydration of fructose to HMF. The protonated N1 and OH-P of the coordinated AMP can form hydrogen bonds with glucose and fructose. This can promote the conversion of the sugars. Sn-AMP has exhibited a superior capability for the conversion of biomass-derived sugars into HMF. The HMF yields of 76.1%, 67.5% and 62.9% were achieved from fructose, glucose, and sucrose, respectively.
