Luminol modified polycarbazole and poly(o-anisidine): Theoretical insights compared with experimental data

Area of Science:

• Materials Science
• Polymer Chemistry
• Optoelectronics

Background:

• Conjugated polymers are crucial for optoelectronic applications.
• Luminol's potential as a multifunctional dopant for polymers is underexplored.
• Tuning polymer properties for specific light emission is a key research area.

Purpose of the Study:

• To investigate the ultrasound-assisted doping of polycarbazole (PCz) and poly(o-anisidine) (PAnis) with luminol.
• To explore the effect of pH (basic, acidic, neutral) on the properties of luminol-doped polymers.
• To characterize the structural, optical, and electronic properties of these novel materials.

Main Methods:

• Ultrasound-assisted doping of PCz and PAnis with luminol.
• Characterization using FT-IR, UV-visible spectroscopy, and X-ray diffraction (XRD).
• Photophysical property investigation via fluorescence spectroscopy and Density Functional Theory (DFT) calculations.

Main Results:

• Luminol doping significantly altered the photo-physical properties of PCz and PAnis.
• The properties of doped polymers varied distinctly in acidic, basic, and neutral media.
• DFT calculations provided insights into structural, optical, and electronic property changes.

Conclusions:

• Luminol acts as a versatile dopant for conjugated polymers.
• The pH-dependent photo-physical characteristics enable tuning of polymer emission.
• This research paves the way for developing tunable near-infrared (NIR) emitting polymers.
