Special Issue Information

Dear Colleagues,

Optical polymers belong to the group of materials that are widely used in photonic technologies. Therefore, significant effort is devoted to both the thorough analysis of existing and the synthesis of new optical polymers, whose special properties can become competitive for many industries.

Due to their isotropy and homogeneity comparable to that of conventional optical glasses, optical polymers are also called organic glasses. The most commonly used representatives of this group of compounds include poly(methyl methacrylate), which is characterized by the highest transparency, polystyrene, which has long been used in optical technology, and polycarbonates, which are characterized by the highest thermal resistance. These materials are characterized by great ease of forming, low price, and the ability to produce large components with complex shapes, difficult to process individually. In addition, they have good visible light transmission, low specific weight, considerable flexibility, and high thermal expansion. The optical properties of such materials may include refractive index, polarization, absorption, luminescence (fluorescence), and transmittance, etc.

One of the most interesting types of advanced optical polymers are those modified with MOFs (metal–organic frameworks). They combine the physical and chemical properties of both inorganic and organic building blocks in fascinating crystal structures with a broad array of functional features. The enormous possibilities of combining and synergistic effects mean that MOFs enable the production of innovative optical implementations characterized by wide functionality.

Aiming to highlight this concept, this Special Issue will focus on the monomeric and polymeric materials currently used in optical technologies, photochemistry, and other related techniques, as well as all kinds of advanced polymeric materials characterized by optical properties.

We kindly invite you to submit manuscripts for this Special Issue. Full papers, communications, and reviews are all welcome.

Polymer materials find many applications in various industries. Efforts are being made to obtain structures with increasingly better properties. It is necessary not only to obtain new materials but also to modify existing structures. Such is the situation with polymer optical fibers. The widespread use of polymer optical fibers is impossible, due to their very high optical losses compared to glass optical fibers. The solution to this problem can be the manufacturing of polymer active optical fibers. Active fibers are the basic components of fiber optic amplifiers and lasers that allow the direct amplification of light inside the fiber. In order for their operation to be the most effective, it is necessary to use dopants. The most commonly used are lanthanide ions isolated from the polymer network, active organic dyes, and quantum dots. These dopants are characterized by very high luminescence and long glow times. Quantum dots of CdSe are made using two organic solvents that differ in boiling points—hexane (a low-boiling solvent with a boiling point of 69 °C) and 1-octadecene (a high-boiling solvent with a boiling point of 315 °C). This work aims to test whether the type of solvent used to obtain quantum dots affects the doping capabilities of polymer structures, from which optical fibers can then be drawn. Full article

Abstract
A series of homogeneous hybrid BPA.DA-NVP@Eu2L3 materials were obtained through an in situ approach where the luminescent dopant was formed at the molecular level with different contents (0.1; 0.2; 0.5; 1; and 2% by weight). A Europium(III) complex (Eu2 [...] Read more.
A series of homogeneous hybrid BPA.DA-NVP@Eu2L3 materials were obtained through an in situ approach where the luminescent dopant was formed at the molecular level with different contents (0.1; 0.2; 0.5; 1; and 2% by weight). A Europium(III) complex (Eu2L3) with quinoline-2,4-dicarboxylic acid was applied as a luminescence additive while a polymer matrix consisted of a combination of bisphenol A diacrylate (BPA.DA) and N-vinylpyrrolidone (NVP) monomers. Synthesis steps and the final materials were monitored by NMR and Fourier transform infrared spectroscopy (FTIR). The emission, excitation spectra, lifetime, and quantum yield measurements were applied for the determination of the photophysical characteristics. The thermal and mechanical properties of the obtained materials were tested via thermal analysis methods (TG/DTG/DSC and TG-FTIR) in air and nitrogen atmospheres, dynamic mechanical analysis (DMA), and hardness and bending measurements. Generally, even a small addition of the metal complex component causes changes in the thermal, mechanical, and luminescent properties. Hybrid materials with a greater europium complex content are characterized by a lower stiffness and hardness while the heterogeneity and the flexibility of the samples increase. A very small amount of an Eu2L3 admixture (0.1% wt.) in a hybrid material causes an emission in the red spectral range and the luminescence intensity was reached for the BPA-DA-NVP@1%Eu2L3 material. These materials may be potentially used in chemical sensing, security systems, and protective coatings against UV. Full article
