Synthetic Sugar-Only Polymers with Double-Shoulder Task: Bioactivity and Imaging

The search for novel fluorescent materials has attracted the attention of many researchers. Numerous bioimaging materials based on the aggregation-induced emission (AIE) units have been surging and could be employed in wide areas during the past two decades. In recent few years, the appearance of nonconventional fluorescence emitters without aromatic conjugated structures provides another bioimaging candidate which has the advantage of enhanced biodegradability and relatively low cost, and their luminescent mechanism can be explained by clustering-triggered emission (CTE) like AIE. In our contribution, we utilize nonaromatic sugar as a monomer to prepare a series of glycopolymers with designed components through sunlight-induced reversible addition fragmentation chain transfer polymerization; these glycopolymers can be employed in bioimaging fields due to the bioactivity coming from sugar and CTE capacity
