Full details of polymer synthesis and characterization can be found in the Supporting Information (SI).
M2F8H18: This block copolymer was synthesized as previously reported.^{8 (link)}M2H18: The synthesis of M2H18 was performed, with slight modification (Scheme S1, Spectra S1-S2), as previously demonstrated by the Mecozzi group.²² M2H10F18: The synthesis of M2H10F13 was performed, with some adaptation (Scheme S2, Spectra S3-S5), as previously demonstrated by the Mecozzi group.²³ M2F13: This block copolymer was synthesized with some modifications to the previous report (Scheme S3, Spectra S6-S8).^{24 (link)}Microwave synthesis reactions were accomplished with an Anton Paar Monowave 300 Microwave Synthesis Reactor (Ashland, VA) equipped with an Anton Paar Autosampler MAS 24. Small molecule and polymer chromatography was accomplished with Silicycle 60 Å SiO₂ or by using a Teledyne CombiFlash® Rf 4x (Lincoln, NE) equipped with an ELSD for visualization and REDI-sep Rf high performance silica or C18 columns. ¹H- and ¹⁹F-NMR spectra were obtained on a Varian Unity-Inova 400 MHz. or Varian Unity-Inova 500 MHz. or Bruker Avance III HD 400 MHz. spectrometer using CDCl₃ as the solvent and TMS as the internal reference. Polymer purity was confirmed by MALDI-MS on a Bruker Ultraflex III MALDI TOF/TOF using α-cyano-4-hydroxycinnamic acid (CHCA) matrix at a ratio of 10:1 matrix: analyte.
