“…This will enable chalcone derivatives to have more interesting properties, including better thermal stability and resistance capacity than cinnamoyl groups. However, most research work has focused on compounds with chalcone groups embedded in the main chain or pended as side chains [29][30][31][32][33][34][35][36]. As the chalcone groups of the dichalcone functionalized monomer can be dimerized under UV light irradiation, it is theoretically possible to obtain linear polymers if the reaction takes place intermolecularly [19,37,38].…”

A series of chalcone derivatives in which two chalcone groups are attached by alkyldioxy chains were synthesized and characterized by 1 H NMR, UV-Vis, and Fourier transform infrared (FTIR) spectral analysis. Upon the irradiation of 365-nm UV light, the chalcone groups in the molecules underwent [2p ? 2p] photodimerization. The photocrosslinking properties were investigated both in solution and in polymethyl methacrylate (PMMA) solid films on quartz plate. It has been found that the photocrosslinking rates of the compounds depended on the different flexibility of the functional groups, which was determined by the length of the spacer chain between the two chalcone moieties. The longest soft chain containing derivatives has a faster photocrosslinking rate both in solution and in solid film. Irradiated by polarized ultraviolet light (PUV), all of the films doped with bis-chalcone derivatives showed an anisotropic absorption property, which may give a promising application as LC-alignment materials.

“…A solution of 1 mole of compound 2 and 1 mole of sodium hydroxide in methanol was constantly stirred at room temperature. Then 1 mole of the corresponding aldehyde was dissolved in the required amount of methanol; it was slowly added with constantly stirred solution for 4 h . After that the reaction mixture was refluxed for 12 h. After cooling to room temperature, the mixture was poured into cold water and neutralized with 10% HCl.…”

Herein, we report four metal-free organic polymethacrylates (In-In-BzI)PMA, (Ac-In-BzI)PMA, (TPA-In-BzI)PMA, and (Py-In-BzI)PMA with pendant chromophores donor-pconjugated-acceptor (D-p-A) molecular framework as photosensitizers for dye-sensitized solar cells (DSSCs). In which the donor-acceptor units are attached by an indole-chalcone extending side chain to inhibit back electron transfer and charge recombination; the p-linker component contains varied chalcone-based substituents to enhance the sunlightharvesting ability of the solar device. Photon-current cells based on the DSSC format were fabricated using the polymers as sensitizers. The DSSC device assembled using (TPA-In-BzI)PMA exhibits a considerably better IPCE peak and J-V response, with an overall power conversion efficiency of 3.70% under the illumination of AM 1.5G (100 mW cm -2 ).

“…based photocrosslinkable polymers were prepared by polymerizing 4-acryl amidophenyl-2',3'-benzostyryl ketone or 4acrylamidophenyl-4'-N,N'-dimethylstyryl ketone in ethyl methyl ketone using benzoyl peroxide as the initiator (Selvam et al 2005). Thermal stability, effect of different solvents and concentration of polymers on the rate of photocrosslinking were also assessed for using the polymers as negative photoresist materials.…”

Polymer nanocomposites (PNCs) are a class of thermo or thermosetting polymers reinforced with small quantities of nano-sized particles to achieve desirable properties such as high thermal, mechanical and flame retardant properties. The present article focuses the different types of photosensitive polymers employed in the production of polymer nanocomposites for photoresist applications. Polymer nanocomposites having photoresist materials show shape dependent properties due to the presence of various photosensitive moieties which after photoirradiation and processing in the specific areas show appropriate solubility. Advanced synthetic methods geared to the needs of today's photoresist applications in fields such as photolithography, advanced microelectronics, medical fields, photo recorders, liquid crystalline displays, holographic display non-linear optical materials.
