Synthesis and Nonlinear Optical Properties of Novel T-type Polyester Containing Thiophene with Enhanced Thermal Stability

“…Infrared (IR) spectra were taken on a Shimadzu FT IR-8201PC infrared spectrophotometer. 1 H NMR spectra were obtained on a Varian 300MHz NMR spectrometer. UV-visible absorption spectra were measured on a Shimadzu UV-3100S spectrophotometer.…”

“…[1][2][3] Among them, NLO polymers are considered candidate materials, mainly because they offer many advantages such as higher nonlinear optical activity, faster response time, high optical damage threshold, low cost, and good processability to form electro-optic devices. One of the current tasks is to design novel NLO polymers having optimized properties.…”

Preparation of Novel T-type Polyurethanes with High Thermal Stability of Second Harmonic Generation and Their Nonlinear Optical Properties

“…1,2 Inorganic materials such as lithium niobate have many disadvantages such as slow response time and degradative photorefractive effects, which limit their applications. NLO polymers, on the other hand, are considered candidate materials, mainly because they offer many advantages such as mechanical endurance, light weight, chemical resistance, and good processability to form optical devices.…”

Synthesis of Novel Y-type Nonlinear Optical Polyester with Enhanced Thermal Stability of Second Harmonic Generation for Electro-Optic Applications

“…[1][2][3][4][5][6] A potential NLO polymer has to be mechanically very strong and thermally stable with a high glass-transition temperature (Tg). In the developments of NLO polymers for electro-optic device applications, stabilization of electrically induced dipole alignment is one of important criteria; in this context, two approaches have been proposed to minimize the randomization of dipole alignment, namely the use cross-linking method [7][8][9][10][11] and the utilization of high T g polymers such as polyimides.…”
