Area of Science:

• Materials Science
• Polymer Chemistry
• Organometallic Chemistry

Background:

• Emissive organometallic polymers combine photoluminescence with polymer properties.
• Functional materials with tunable optical and mechanical characteristics are in high demand.

Purpose of the Study:

• To develop novel organometallic polymers with enhanced emissive and mechanical properties.
• To investigate the vapoluminescent behavior and sensing capabilities of these new materials.

Main Methods:

• Mechanical grinding of an emissive organometallic complex, [CuBr(PPh3)2(4-methylpyridine)], into a random copolymer of 4-(diphenylphosphino)styrene (DPVP) and n-butyl acrylate (BA).
• Characterization of the resulting hybrid materials for photoluminescence and mechanical properties.
• Testing the vapoluminescent response to various organic solvent vapors.
• Evaluation of the material as a sensor for volatile chemical compounds (VOCs).

Main Results:

• Successful incorporation of emissive copper complexes into a polymer matrix, acting as crosslinkers.
• Demonstration of excellent vapoluminescent properties with rapid photoluminescence loss and recovery upon exposure to solvent vapors.
• Fabrication of mechanically robust and flexible films with high sensitivity for VOC detection.
• Achieved low limits of detection (LOD) for VOCs like toluene, acetone, chloroform, and dichloromethane.

Conclusions:

• The developed organometallic polymers exhibit promising vapoluminescent sensing capabilities for hazardous VOCs.
• Mechanical robustness and flexibility make these materials suitable for practical sensor applications.
• This work provides insights into designing and fabricating advanced organometallic polymers for diverse applications.
