MUMBAI, India, Feb. 27 -- Intellectual Property India has published a patent application (202531016010 A) filed by Indian Institute Of Technology, Kharagpur, West Bengal, on Feb. 24, 2025, for 'low-cost synthesis of soluble bay-substituted terrylene and polyterrylene homopolymers.'
Inventor(s) include Samanta, Suman Kalyan; and Ghosh, Chitrak.
The application for the patent was published on Feb. 27, under issue no. 09/2026.
According to the abstract released by the Intellectual Property India: "The present invention proposes a facile route to synthesize 7,8-bis(alkyloxy)terrylenes, a terrylene scaffold substituted with two alkoxy chains at the 7 and 8 bay-positions. The Suzuki-Miyaura cross-coupling reaction is replaced by Grignard-Kumada reaction sequence which is economically more favorable. Also, a dehydrohalogenation reaction in the second step is very facile with higher yields and does not produce any other terrylene isomers. After successful synthesis of terrylene molecules, the bromination reaction is performed to obtain dibromo derivative of terrylene. A facile Yamamoto homocoupling reaction of dibromoterrylene provides polyterrylene, homopolymers of terrylene."
