Abstract:
PET-RAFT (photoinduced electron/energy transfer – reversible addition/fragmentation chain transfer) technology is one of living radical polymerization methodologies controlled by visible light and (near) IR light, which merges the tranditional RAFT polymerization with photoredox catalysis. In this technology, ppm amount of photoredox catalyst is employed to catalyze RAFT agent and generate radicals for subsequent polymerization, instead of external radical initiator in the traditional RAFT method. The RAFT agent plays the role of initiator, chain transfer agent and termination agent.
Although slight modification to RAFT polymerization was made, it brings many “green” and significant attributes to living radical polymerizations, including: (1) low energy consumption and mild reaction conditions, (2) spatial and temporal control on radical polymerization, (3) high oxygen tolerance, (4) versatile photocatalysts and (5) selective polymerization activation. In this talk, the benefits from PET-RAFT technology will be summarized and its practical applications in green and precision polymerization will be described in full details. The potential opportunities for the innovation of new development in organic and polymer synthesis will be overviewed.
Biography:
Dr. Jiangtao Xu is an ARC Future Fellow and Lecturer in School of Chemical Engineering, UNSW Sydney. He is currently leading a research group in the Centre for Advanced Macromolecular Design (CAMD) and Australian Centre for NanoMedicine (ACN), with the focus on green and precision polymer synthesis using state-of-the-art polymerization techniques and organic chemistry tools. Dr. Xu received his bachelor (2001) and PhD degree (2007) in polymer chemistry from Fudan University in China, where he focused on developing RAFT polymerization. Following the postdoctoral research in UNSW Australia (2007-2010) and the University of Melbourne (2011-2012) and industrial experience (2012-2013), he joined UNSW again (2014) and developed PET-RAFT technique (Photoinduced Electron/Energy Transfer - RAFT), which has been widely recognized and used by the peers in the community. His current research interests include: (1) green chemistry and sustainable polymer synthesis; (2) precision polymer synthesis mimicking natural perfection; (3) photoredox catalysis for living polymerization and (4) advanced polymer materials for nanomedicine and bioengineering applications.
