The mechanism of reversible photodegradation of 1-substituted aminoanthraquinones doped into poly(methyl methacrylate) and polystyrene is investigated. Time-dependent density functional theory is employed to predict the transition energies and corresponding oscillator strengths of the proposed reversibly and irreversibly damaged dye species. Ultraviolet-visible and Fourier transform infrared (FTIR) spectroscopy are used to characterize which species are present. FTIR spectroscopy indicates that… 
Recovery of photodegraded rhodamine 6g in ester-containing polymer matrices.
Recovery of the ASE signal is observed in dye-doped thermoplastic polyurethane and glycol-modified poly(ethylene terephthalate); both polymers contain repeating ester groups in their backbone to mediate the full recovery of rhodamine 6g from a photodegraded state.
Photochemical Properties and Stability of BODIPY Dyes
The present study is devoted to the combined experimental and theoretical description of the photophysical properties and photodegradation of the new boron-dipyrromethene (BODIPY) derivatives
Imaging studies of photodegradation and self-healing in anthraquinone derivative dye-doped PMMA.
1,8-dihydroxyanthraquinone (Dantron/Chrysazin) is found to be having the best photostability and recovery characteristics of all dyes tested in this study, and three rules-of-thumb are developed to qualitatively predict the photostabilities and Recovery characteristics of anthraquin one derivatives.
Imaging studies of temperature dependent photodegradation and self-healing in disperse orange 11 dye-doped polymers.
While the temperature dependence predictions of the modified correlated chromophore domain model (mCCDM) are confirmed, it is found that it is quantitatively incompatible with the mCCDM as recovery in DO11/PS is found to behave as a stretched (or double) exponential as a function of time.
Design of PMMA Doped with Inorganic Materials as Promising Structures for Optoelectronics Applications
In this work, studying the effect of adding nanoparticles on the optimized geometrical parameters, electronic and spectroscopic properties of pure (PMMA), (PMMA-Al2O3), (PMMA-ZrO2), (PMMA-Al2O3-Ag)
Optical Characterization of Doped Thermoplastic and Thermosetting Polymer-Optical-Fibers
The emission properties of a graded-index thermoplastic polymer optical fiber and a step-index thermosetting one, both doped with rhodamine 6G, have been studied and comparisons between the results are presented and discussed.

Demonstration of a self-healing all-polymer distributed Bragg reflector laser
Self-healing of an all-polymer distributed Bragg reflector laser is demonstrated. The lasing medium is a glycol-modified poly(ethylene terephthalate) co-polymer doped with rhodamine 6G. After the


The role of the polymer host on reversible photodegradation in Disperse Orange 11 dye
The photodegradation and recovery process in anthraquinone chromophores have been characterized using am plified spontaneous emission (ASE) in several Anthraquinone derivatives doped in poly(methyl
Mechanisms of reversible photodegradation in disperse orange 11 dye doped in PMMA polymer.
An energy level diagram is constructed that describes all measured quantities in the decay and recovery processes and a hypothesis of the nature of the associated states is proposed.
Studies on the photooxidation mechanism of polymers. II. The role of quinones as sensitizers in the photooxidative degradation of polystyrene
During the quinone-sensitized photooxidative degradation of polystyrene film and its solution in benzene, an initial rapid decrease of average molecular weight has been observed by GPC and viscosity
Mechanism of the photocycloaddition of 1-aminoanthraquinones to olefins by visible light irradiation; oxetan formation via an exciplex
The mechanisms of the photocycloadditions of 1-aminoanthraquinone (1) and 1-amino-2,4-dibromoanthraquinone (2) to olefins by visible light irradiation have been investigated. Fluorescence of compound
The Polarized Absorption Spectra of Some α-Aminoanthraquinones
The π–π* electronic absorption spectra of 1-amino-, 1,4-diamino-, and 1,4,5,8-tetraaminoanthraquinones were investigated by means of the polarized absorption spectra using stretched PVA sheets and
Synthesis, redox properties, and basicity of substituted 1-aminoanthraquinones: spectroscopic, electrochemical, and computational studies in acetonitrile solutions
Abstract1-Amino-, 1-ethylamino-, and 1-(diethylamino)-anthraquinone were characterized by UV–Vis spectroscopy, acid–base titration, electrochemical methods, and quantum-chemical (QM) calculations at
The role of polymer-mediated dopant correlations in damage moderation and self healing
The fact that chromophores doped into a polymer self heal after photodegradation seems to contradict the common understanding that molecular damage is a thermodynamically irreversible process. We
The Polarized Absorption Spectra of Some β-Substituted Anthraquinones
The polarized absorption spectra of 2-hydroxy-, 2-amino-, and 2,3-diaminoanthraquinones were measured in stretched PVA sheets below 47 kK, and semiempirical ASMO-SCF-CI calculations, including the
