We used fluorescence spectroscopic measurements as a probe to study the self-healing properties of anthraquinone derivative molecules doped in poly(methyl methacrylate) (PMMA). 2,4-Dibromoanthraquinone dye doped in PMMA recovers after photodegradation. Its dynamics differs from other anthraquinone derivative molecules. This could be due to the relatively heavier bromine atom attached to one of the carbon atoms of the benzene ring. In this article, we will discuss the self-healing properties of…

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


Correlation between molecular structure and self-healing in a series of Anthraquinone derivatives doped in PMMA polymer
We observe that many different derivatives of anthraquinone chromophores doped in PMMA self heal after undergoing photodegradation. We are interested to know the mechanisms that are responsible for
Experimental tests of a new correlated chromophore domain model of self-healing in a dye-doped polymer
Temperature-dependent photodegradation and recovery studies of Dipserse Orange 11 (DO11) dye dissolved in poly(methyl methacrylate) and polystyrene polymer hosts are used as a test of a new model
A self healing model based on polymer-mediated chromophore correlations.
A model of self healing in which correlations between chromophores, as mediated by the polymer, are key to the recovery process is presented, and the size distribution of the correlation volume is determined using a grand canonical ensemble through a free energy advantage parameter.
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.
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
The photochemistry of the self-healing chromophore Disperse Orange 11
Recent interest in the self-healing ability of the laser dye 1-amino-2-methylanthraquinone, Disperse Orange 11, has lead us to investigate the possible alternative mechanisms of action, either
The polymeric electro-optical stilbene material, 4-dimethylamino-4′-nitrostilbene (DANS), was illuminated at wavelengths ranging from the visible to near-infrared in order to quantify its
Testing the diffusion hypothesis as a mechanism of self-healing in Disperse Orange 11 doped in poly(methyl methacrylate)
In this work, we show that reversible photodegradation of Disperse Orange 11 doped in poly(methyl methacrylate) is not due to dye diffusion—a common phenomenon observed in many dye-doped polymers.
Photonics and molecular design of dye-doped polymers for modern light-sensitive materials
Abstract The advantages of dye-doped polymer matrices over polymers and dyes, separately, are analyzed. The effects of the polymer nature and chemical constitution of organic dyes on the spectral and
