Perfluorophenyl‐Terpyridine Ruthenium Complex as Monomer for Fast, Efficient, and Mild Metallopolymerizations

Abstract

Herein, the new concept of thiol-para-fluorine "click" chemistry is employed for the formation of ruthenium(II) bisterpyridine metallopolymers in a fast and efficient manner. In general, the assembly of comparable metallopolymers requires high temperatures and long reaction times. In contrast to established methods, when utilizing a pentafluorophenyl-substituted homoleptic Ru(II) bisterpyridine complex, as a monomer, thiol-functionalized organic spacer units can easily be introduced at low temperatures and in very short reaction times. Furthermore, alternating arrangements of different metal ions (e.g., Ru(II) and Fe(II)) in metallopolymers can be achieved.

Para-Fluoro Postpolymerization Chemistry of Poly(pentafluorobenzyl methacrylate): Modification with Amines, Thiols, and Carbonylthiolates

“…[15][16][17] Low molar mass PFB derivatives have been used for the synthesis of monomers 18 and for polymer end group modification. 19 Multifunctional PFB-functional building blocks have been condensed for the preparation of metal-containing linear polymers, 20 hyperbranched polymers, 21 and precision networks. 22 PFB-functionalised end groups were exploited for the functionalization of polythiophenes 23 and the synthesis of multi-arm copolymers.…”

Fluor-thiol Photocoupling Reaction for Developing High Performance Nucleic Acid (NA) Microarrays

“…Nevertheless, poor surface wettability can hamper proper contact between the groups on the surface and the probes in the solution by lowering immobilization yields and hindering effective hybridization. 17,18 Although the use of perfluorinated surfaces is challenging, it can be very useful for applications in microarray technology, among others [19][20][21][22] In fact in this study we report the fluor-thiol photocoupling reaction to covalently bond thiolated probes directly to a perfluoroalkyl surface for the first time. This methodology allows the probes bearing a thiol group to be anchored to the C-F bond of highly hydrophobic surfaces quickly and cleanly.…”
