In situ monitoring of PISA morphologies. Rho, J. Y., Scheutz, G. M., Hakkinen, S., Garrison, J. B., Song, Q., Yang, J., Richardson, R., Perrier, S., & Sumerlin, B. S. POLYMER CHEMISTRY, 12(27):3947–3952, July, 2021. doi abstract bibtex Polymerization-induced self-assembly (PISA) is a facile method to obtain block copolymer aggregates with defined morphologies. However, the transitions between these morphologies have been difficult to monitor directly in real-time during the polymerization. Herein, we describe a straightforward and readily accessible in situ method to monitor the evolution of nanostructure via changes in internal hydrophobicity during the PISA process using a polymer-tethered pyrene fluorescent probe. We were able to correlate morphological transitions with changes of the pyrene emission and gain unprecedented insight into the evolution of core hydrophobicity during PISA.
