Pyrroloquinoline Based Styryl Dyes Doped PMMA, PS, and PS/TiO2 Polymer for Fluorescent Applications

Abstract

This article presents two highly fluorescent donor-π-acceptor (D-π-A) moieties containing an electron-donating carbazole and phenothiazine donors fused with electron-withdrawing pyrrolo-quinoline acceptor dyes, PQC and PQPT . We also discussed the polymerization and film-forming process of dye PQC and PQPT doped in poly (methyl methacrylate) (PMMA) and polystyrene (PS) polymer to find their optical applications in polymer-based technology. We investigated the fluorescent properties of dyes PQC and PQPT from 0.01 to 1 wt% in poly(methyl methacrylate) (PMMA). We also investigated the changes in the spectrum shape and shift in wavelength with changes in poly(methyl methacrylate) (PMMA), polystyrene (PS), and TiO 2 doped in polystyrene (PS/TiO 2 ). The analysis of surface morphology of prepared polymer samples was done with the help of a scanning electron microscope. The thermal and photostability of synthesized dyes in poly (methyl methacrylate) (PMMA), polystyrene (PS), and TiO 2 doped in polystyrene (PS/TiO 2 ) were investigated to get detailed information owing to the application of fluorescent polymers in the field of optoelectronic, nanohybrid coatings in solar concentrators, etc. Graphical Abstract

Hybrid Organic–Inorganic PMMA Optical Fibers Functionalized with Photochromic Active WO3 Nanoparticles: From Materials Design to Photochromic Fabrics

“…Some organic/inorganic composites have also been known to show trends similar to the ones reported here in the glass transition increment upon doping with various nanoparticles. [ 45 ] Hammani et al [ 46 ] showed an enhancement in T g by up to 60 °C with increasing ZnO NPs loading in PMMA matrix from 0 to 40%wt. They found that the dispersion of ZnO NPs in the PMMA matrix hinders the movement of macromolecules and increases the T g of the sample.…”
