4,4’-Dibenzoic acid is one of the important monomers for the synthesis of general-purpose high-performance polymers and liquid crystal materials [1]. However, this monomer has shortcomings such as long industrial synthesis route, heavy pollution, low selectivity, and poor biodegradability of the synthesized polymer. Under increasingly severe environmental control and carbon neutrality restrictions, its industrial production and polymer application have become increasingly difficult. Subject to many restrictions. Therefore, it is of great significance to develop alternatives to 4,4’-bibenzoic acid. Among them, 2,2'-bifuran-5,5'-dicarboxylic acid (BFDCA) and its derived diesters are similar in structure to 4,4'-dibenzoic acid, and are both derived from agricultural by-products and are simple to synthesize. The conditions are mild and the corresponding polymer is biodegradable, making it an excellent substitute for 4,4'-biphenyldicarboxylic acid.
2,2'-Difuran-5,5'-dicarboxylic acid monomer and its derived diester can undergo polymerization reactions with aliphatic diols, diamines, aromatic diphenols, diamines, etc., and are used for synthesis Various polymer materials can also be used in the synthesis of various copolymer compounds. The resulting polymers exhibit good mechanical strength and liquid crystal behavior. For example, polymers obtained by polymerizing BFDCA with ethylene glycol exhibit significantly lower liquid crystalline behavior than the corresponding biphenyldicarboxylic acid polymers and have better machining properties (Figure 1) [2][2][2]
Diethyl 2,2'-bifuran-5,5'-dicarboxylate monomer can polymerize with aliphatic and aromatic diols/diamines at lower temperatures than BFDCA. In addition, it can be copolymerized with other monomers, allowing for the flexible synthesis of multifunctional polymers.
