MUMBAI, India, Jan. 9 -- Intellectual Property India has published a patent application (202541133637 A) filed by Indian Institute Of Technology, Hyderabad, Telangana, on Dec. 30, 2025, for 'benzo[4,5]thieno[3,2-d]thiazole-based donor-acceptor-donor (d-a-d) compound and a process of prepartion thereof.'
Inventor(s) include Sivakumar Vaidyanathan; Biswaranjan Sahu; Diksha Thakur; Panneerselvam Yuvaraj; and Ram Awatar Maurya.
The application for the patent was published on Jan. 9, under issue no. 02/2026.
According to the abstract released by the Intellectual Property India: "The present disclsoure relates to donor-acceptor-donor (D-A-D) organic compounds for optoelectronic applications, particularly organic light-emitting diodes (OLEDs). The invention discloses a sulfur-rich fused heteroaromatic acceptor core, benzo[4,5]thieno[3,2-d]thiazole based D-A-D compounds, exhibiting an intrinsically shallow highest occupied molecular orbital (HOMO) energy level, thereby enabling efficient hole injection without additional interfacial layers. By maintaining a fixed acceptor core and systematically varying the strength of secondary donor units, controlled redistribution of the HOMO is achieved, while the lowest unoccupied molecular orbital (LUMO) remains localized on the acceptor core. The present disclosure also relates to a process of preparing a benzo[4,5]thieno[3,2-d]thiazole based D-A-D compounds."
