MUMBAI, India, Aug. 24 -- Intellectual Property India has published a patent application (202641098518 A) filed by Indian Institute Of Technology Hyderabad on August 14, 2026, for Quinoline-Based Organic Fluorophore And The Method Of Preparation Thereof.
Inventors include Sivakumar Vaidyanadhan; Prathap Rangasamy; Sandhya Rani Nayak; and Swetha Maredi.
The application for the patent was published on August 21, 2026, under issue no. 34/2026.
Abstract: ABSTRACT QUINOLINE-BASED ORGANIC FLUOROPHORE AND THE METHOD OF PREPARATION THEREOF The present invention relates to a quinoline- based organic fluorophores and a hybrid white-light-emitting device comprising the same. The fluorophores comprise donor-acceptor (D-A) or donor-acceptor-donor (D-A-D) architectures incorporating a quinoline-based acceptor and anthracene and/or diphenylamine donor units. The fluorophores exhibit tunable absorption and emission characteristics and hybridized local and charge-transfer (HLCT) excited-state behaviour. The fluorophores exhibit fluorescence quantum yields in the range of 32 to 85% and average fluorescence lifetimes in the range of 3 to 5 ns. The invention further provides processes for preparing the quinoline-based organic fluorophores. Fig. 1
