Problem
There is a need for tunable organic optical materials that can operate in liquid and solid forms while adding useful photonic functions to a polystyrene matrix.
Why it matters
A polymer-compatible gain material with temperature-dependent emission could create new options for laser media, optical coatings, and photonic sensing research.
Approach
The material places a defined chalcone and 2-hydroxyethyl methacrylate units within a polystyrene matrix, with preparation routes for liquid and solid products that exhibit specified laser and fluorescence signals.
Who may benefit
Potential beneficiaries include photonics laboratories, specialty-polymer producers, laser-material developers, optical-coating companies, and sensor researchers.
Potential value
The disclosed composite combines a polystyrene host, a covalently associated chalcone chromophore, and a methacrylate linker, with claimed optical outputs in both liquid and solid formats and a temperature-dependent laser response.
Background
Background
Polystyrene is widely used but has limited intrinsic optical functionality, while chalcones are conjugated compounds whose photophysical properties can be tuned through molecular structure, solvent, concentration, and excitation. Prior chalcone systems have been investigated as laser media or fluorescent sensors. The patent incorporates a specific dimethylamino chalcone and 2-hydroxyethyl methacrylate into a polystyrene matrix. Its stated objective is a thermal laser medium and a smart coating, and the claims provide preparation conditions plus liquid-state, solid-state, fluorescence, melting, and temperature-dependent laser measurements.
Technology overview
Technology overview
The chalcone 1-(2H-1,3-benzodioxol-5-yl)-3-[4-(dimethylamino)phenyl]-(2E)-propan-1-one is mixed with 2-hydroxyethyl methacrylate. Polystyrene is dissolved in a polar organic solvent, including tetrahydrofuran, and the solutions are combined at 80–100 °C. Cooling for 30–90 minutes yields a liquid with claimed signals at 555–565 and 580–590 nm. Additional heating at 130–170 °C and extended cooling yields a solid with signals at 545–555 and 580–590 nm, fluorescence at 530–540 nm, and temperature-dependent intensity.
