CAS:653-34-9 | 2,3,4,5,6-Pentafluorostyrene ,Description

2,3,4,5,6-Pentafluorostyrene, otherwise known as PFS, is a fluorinated aromatic monomer that has been widely studied and utilized in various scientific and industrial applications. It is a versatile monomer with a wide range of properties, including excellent thermal stability, relatively low volatility, and high solubility in many organic solvents. The monomer is also highly reactive, making it a useful building block for the synthesis of polymers and other materials. 
 

Scientific Research Applications

Copolymer Synthesis

2,3,4,5,6-Pentafluorostyrene (PFS) is effectively used in the synthesis of copolymers. For instance, it has been combined with N-phenylmaleimide to produce copolymers with high hydrophobicity and high glass transition temperatures (Agarwal, Becker, & Tewes, 2005). Similarly, copolymerization with β-pinene yielded copolymers with single glass transitions, high water contact angles, and optical activity (Paz-Pazos & Pugh, 2006).

Surface Modification

PFS is also instrumental in surface modification techniques. For example, the creation of low surface energy polymer brushes of PFS on silicon wafer surfaces demonstrates its utility in modifying surface properties (Feng-ling, 2008). Additionally, fluorine-contained copolymer ultra-thin films made from PFS exhibit excellent stability and corrosion resistance (Luo et al., 2010).

Functionalization and Applications

PFS has been utilized in multifunctionalization processes, as seen in the orthogonal multifunctionalization of random and alternating copolymers synthesized from PFS and propargyl-containing styrene derivatives (Ten Brummelhuis & Weck, 2012). Furthermore, copolymers of PFS have been investigated for their potential as antibiofouling coatings, showing decreased surface energy and reduced protein adsorption (Ha et al., 2018).

Sensory Applications

PFS has been incorporated in the development of stable optical oxygen sensing materials. Copolymers of styrene and pentafluorostyrene containing PFS were used to create sensor materials with linked indicators, effectively eliminating dye migration and leaching (Koren, Borisov, & Klimant, 2012).

Additional Functional Uses

Further applications include the fabrication of superhydrophobic surfaces and fluorinated microspheres (Muñoz-Bonilla et al., 2010), and the synthesis of novel fluorine-containing poly(aryl ether nitrile)s derived from PFS (Kimura et al., 2001).
