What is it about?
The article shows an easy way to functionalize poly(DL-lactide) with phenolic dyes. The polymer-dye-hybrids are analysed for their performance to protect eyes or sensors from laser damage. They have good nonlinear optical properties and are like that very effective.

Why is it important?
Phenolgroups are somethimes thought to be not so effective as initiators for Ring-opening-polymerization, but they are not only effective, but also allow high the production of high molecular weight polymers.
