MUMBAI, India, Feb. 13 -- Intellectual Property India has published a patent application (202511132537 A) filed by Indian Institute Of Technology Roorkee; and Enrgenv Smart Chemicals And Materials Pvt. Ltd., Roorkee, Uttarakhand, on Dec. 27, 2025, for 'an organic polymer based photodetector for ultraviolet detection fabricated using heteroatom(s) enriched polytriazines.'
Inventor(s) include Ms. Tanya Gupta; Mr. Akshaykumar Dipchand Salunke; Dr. Santanu Pradhan; and Prof. Paritosh Mohanty.
The application for the patent was published on Feb. 13, under issue no. 07/2026.
According to the abstract released by the Intellectual Property India: "The present invention relates to an organic UV photodetector fabricated using nitrogen-enriched nanoporous polytriazine (NENP) deposited on Au electrodes over a SiO2/Si substrate. pH modulation of the polymer significantly enhances its electronic and optoelectronic properties. The optimized NENP-pH3 device exhibits ultrafast response time and long-term stability, with no appreciable degradation of the material or its performance. A portable device fabricated using NENP-based UV OPDs converts photocurrent into a visible indication of UV intensity, comprising a microcontroller unit (MCU) interfaced with multiple LED driver outputs. The dedicated connectors (D1-D3) are provided for LED connections while resistors (R4, R7, R8) regulate current flow to ensure stable operation of the respective LEDs. The capacitor (C1) is incorporated for power stabilization, a battery input is provided for portable operation and passive components (R1) and a detector unit (U2) for biasing and feedback control at the rear side."
