Photoresponsive soft materials are everywhere in the nature, from human's retina tissues to plants, and have been the inspiration for engineers in the development of modern biomedical materials. Light as an external stimulus is particularly attractive because it is relatively cheap, noninvasive to superficial biological tissues, can be delivered contactless and offers high spatiotemporal control. In the biomedical field, soft materials that respond to long wavelength or that incorporate a photon upconversion mechanism are desired to overcome the limited UV-visible light penetration into biological tissues.

- The study focuses on the coordinative chain transfer polymerization (CCTP) of biobased terpenes, specifically myrcene and farnesene, using a specialized Ziegler-Natta catalyst system.
- The process achieved over 85% yield, indicating efficient monomer conversion, and the kinetics suggested a reversible chain transfer mechanism when using a certain amount of cocatalyst/chain transfer agent.
- The resulting polyterpenes exhibited controlled molecular weight distributions and a high percentage of desired 1,4-microstructure, essential for improving polymer properties.
