  Synthesis and characterization of thianthrene-based epoxy with high refractive index over 1.7

  摘要：

  A novel glycidyl resin 2,7-bis(-epoxypropylthio)thianthrene (4SEP) with high refractive index was synthesized and characterized by H-1 NMR, FT IR and FD-MS analyses. The kinetics of 4SEP cured with methylhexahydrophthalic anhydride (MeHHPA) was investigated by nonisothermal differential scanning calorimetry. The results revealed that the reactivity of 4SEP was higher compared with that of diglycidyl ether of bisphenol A (DGEBA) due to the weakened electron-withdrawing effect of thioether on the epoxy group. The thermal properties and refractive index of 4SEP/MeHHPA were investigated with differential scanning calorimetry, thermogravimetric analyses, Abbe refractometer, prism coupler, and compared with those of the DGEBA/MeHHPA. Experimental results showed that, due to the introduction of thianthrene and thioether units, the glass transition temperature (T-g) was slightly enhanced, while the thermal stability was reduced. The refractive index of 4SEP was over 1.7000, and the refractive index of 4SEP/MeHHPA was up to 1.6808.

  A highly refractive, transparent, and totally colorless poly(phenylene thioether) (PPT) containing a triazine unit has been developed. A new aromatic dithiol, thianthrene-2,7-dithiol, with a high sulfur content was designed and synthesized in order to develop PPTs with high refractive indices and high glass transition temperatures (Tgs). These PPTs were prepared by the phase-transfer catalyzed polycondensation

  已经开发了包含三嗪单元的高折射，透明且完全无色的聚苯硫醚（PPT）。为了开发具有高折射率和高玻璃化转变温度（T g s）的PPT，设计并合成了一种具有高硫含量的新型芳香族二硫醇，蒽-2,7-二硫醇。这些PPT是通过2,4-二氯-6-烷硫基1,3,5-三嗪与芳族二硫醇如4,4'-硫代双苯硫醇，苯-1,3-二硫醇和蒽-2,7-二硫醇。由2,4-二氯-6-甲硫基1,3,5-三嗪和芳香族二硫醇制得的PPT具有良好的热稳定性，例如在120°C时具有较高的T g s和5％的失重温度（T 5％）在350°C左右。厚度为1μm的聚合物薄膜在400 nm处的透光率约为98％。三嗪和含硫的蒽单元的组合提供了在633 nm处具有高达1.7720的高折射率和低双折射（<0.005）的PPT。

  The disclosure provides thianthrene derivatized monomers and polymers for use in volume Bragg gratings, including, but not limited to, volume Bragg gratings for holography applications. Several thianthrene structures are described, including structures substituted by halogens, sulphur containing groups, phenyl groups, at least one polymerizable group, etc. Thianthrene derivatized polymers in Bragg gratings applications lead to materials with higher refractive index, low birefringence, and less packing in solid state. Thianthrene derivatized monomers/polymers can be used in any volume Bragg gratings materials, including two-stage polymer materials where a matrix is cured in a first step, and then the volume Bragg grating is written by way of a second curing step of a monomer.
