Synthesis of fluorescence‐labelled short‐chain polyester segments for the investigation of bioresorbable poly (ester‐urethane) s

The synthesis and characterization of fluorescence-labelled low-molecular-weight polyesters based on known biocompatible and degradable materials such as poly [(R)-3- hydroxybutyric acid](PHB) and poly (ε-caprolactone-co-glycolide) is described. A telechelic OH-terminated poly [(R)-3-hydroxybutyric acid](M n= 2300) was modified at the end groups through esterification with BOC-glycine. After removal of the BOC protection, the so-obtained free amino groups were conjugated with dansyl chloride to obtain dansyl-labelled end ...
