MUMBAI, India, Jan. 9 -- Intellectual Property India has published a patent application (202541134362 A) filed by Indian Institute Of Technology, Hyderabad, Telangana, on Dec. 31, 2025, for 'luminescent organometallic copper(i) complexes and the method of preparation thereof.'
Inventor(s) include Ganesan Prabusankar; Gopendra Muduli; Joginder Singh; Bikash Lahkar; Amitkumar Ramakant Girbide; Dinesh Harijan; and Rakesh Kumar Rai.
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 invention relates to a class of luminescent organothione-stabilized copper(I) complexes and coordination polymers exhibiting tunable solid-state photoluminescence. The present invention also discloses a method of preparing these complexes. Depending on the nature of the coordinated anion, the copper(I) systems form discrete molecular complexes as well as one-dimensional and two-dimensional hybrid coordination networks. These materials exhibit intense and stable emission in the visible region under ultraviolet excitation, with emission color, lifetime, and quantum efficiency being systematically adjustable by variation of the anion and structural dimensionality. The use of earth-abundant copper, combined with a simple and scalable synthesis, provides environmentally benign and cost-effective luminescent materials suitable for solid-state lighting, optoelectronic devices, display technologies, sensing applications, and photonic systems."
