New crosslinked polymer systems with high and stable optical nonlinearity

Covalent attachment of chromophores to chlorinated copolymers for optical waveguides: Synthesis and optical characterization

“…An attempt to get any product by uncatalyzed reaction of DR19 with GMA was unsuccessful, even at 80 C and with reaction times of 48 h. The reaction was then tested with various catalysts, such as BFEt [42], TiBuO [43], ETPP [44], DMAP [45].…”

“…It is likely that this highly exothermic reaction hinders the detection of the endothermic melting process. It was reported that the vinyl monomers carrying chromophores with -NO 2 groups are rather difficult to undergo radical polymerization because of the inhibition of these groups [44].…”

Investigation of Thermal Properties and Reactivity Ratios of Acetyl Benzofuran Methacrylate Copolymers

“…Polimerler, günümüzde birçok sanayi ve teknolojik uygulama alanına sahip, insan hayatında her alanda kullanılabilen materyallerdir (Yoruç, 2017). Akrilik ve metakrilik polimerlerin optik özelliklere sahip oldukları, lineer olmayan materyaller, elektro fotoğrafik kaplama, mikro elektronik ve sıvı kristal; sanayide çubuk boru, levha ve saydam levha gibi materyallerin yapımında kullanıldıkları bildirilmiştir (Ho, 1992;Zhang, 1999;Mizoguchi ve Hasegawa 1996;Song, 2002;Allen, 1998;Coşkun, 2016). Tıpta; ilaç salınımı, katkı maddesi, ilaç matriks maddesi; polimer kaplamalı ilaç kristallerinin sentezlenmesi, kemoterapi kombinasyonu için polimer ilaç konjugatı, biyolojik aktif özellik amaçlı geniş kullanım alanlarına sahip oldukları belirtilmiştir (Wang, 2014;Chen Y., 2015;Vejani, 2015;Chen D., 2015;Darvishi, 2013;Taylor, 2004, Kawaguchi, 2000İlter, 2015).…”

Optical properties of coumarins containing copolymers

“…Due to inherent photo-chemical characteristics, reasonable stability, good solubility and relative ease of synthesis, coumarin derivatives have been extensively investigated for electronic and photonic applications such as charge-transfer agents, solar energy collectors [1] and potential application in organic light-emitting diodes (OLEDs) [2]. They are useful in many fields such as photoalignment of liquid crystalline molecules [3,4], photoactive surface application [5], electroluminescent materials [6], fluorescence materials and laser dyes [7], two photon absorption materials, reversible optical data storage [8,9], organic-inorganic hybrid materials [10], nonlinear optical materials [11], as well as holographic elements [12]. Appropriately substituted coumarins find application as fluorescent dyes for synthetic fibers and as daylight fluorescent pigments, which impart vivid brilliance to paints and printing inks [1].…”
