  Effects of o-Methoxy Groups on the Properties and Thermal Stability of Renewable High-Temperature Cyanate Ester Resins

  摘要：

  Renewable phenols derived from biomass sources often contain methoxy groups that alter the properties of derivative polymers. To evaluate the impact of o-methoxy groups on the performance characteristics of cyanate ester resins, three bisphenols derived from the renewable phenol creosol were deoxygenated by conversion to ditriflates followed by palladium-catalyzed elimination and hydrolysis of the methoxy groups. The deoxygenated bisphenols were then converted to the following cyanate ester resins: bis(4-cyanato-2-methylphenyl)methane (16), 4,4'-(ethane-1,1'-diy1)bis-(1-cyanato-3-methylbenzene) (17), and 4,4'-(propane-1,1'-diy1)bis(1-cyanato-3-methylbenzene) (18). The physical properties, cure chemistry, and thermal stability of these resins were evaluated and compared to those of cyanate esters derived from the oxygenated bisphenols. 16 and 18 had melting points 37 and >95 degrees C lower, respectively, than the oxygenated versions, while 17 had a melting point 14 degrees C higher. The T-g's of thermosets generated from the deoxygenated resins ranged from 267 to 283 degrees C, up to 30 degrees C higher than the oxygenated resins, while the onset of thermal degradation was 50-80 degrees C higher. The deoxygenated resins also exhibited water uptakes up to 43% lower and wet T(g)s up to 37 degrees C higher than the oxygenated resins. TGA-FTIR of thermoset networks derived from 16-18 revealed a different decomposition mechanism compared to the oxygenated resins. Instead of a low-temperature pathway that resulted in the evolution of phenolic compounds, 16-18 had significantly higher char yields and decomposed via evolution of small molecules including isocyanic acid, CH4, CO2, and NH3.

  A photoactive compound is used in combination with a photosensitizer, represented by the following formula (1): A −[( J ) m −( X-Pro )] n (1) wherein A represents a hydrophobic unit comprising at least one kind of hydrophobic groups selected from a hydrocarbon group and a heterocyclic group, J represents a connecting group, X-Pro represents a hydrophilic group protected by a protective group Pro which is removable by light exposure, m represents 0 or 1, and n represents an integer of not less than 1. The protective group Pro may be removable by light exposure in association with the photosensitizer (especially, a photo acid generator), or may be a hydrophobic protective group. The hydrophilic group may be a hydroxyl group or a carboxyl group. The photoactive compound has high sensitivity to a light source of short wavelength beams, for resist application, therefore, the photoactive compound is advantageously used for forming a pattern with high resolution.

  This study reports a mild and efficient synthetic protocol for the synthesis of symmetrical and unsymmetrical diarylmethanes (DAMs). Using DMSO as the C1 source and TMSOTf as the Lewis acid promoter, a series of functionalized symmetrical and unsymmetrical DAMs were synthesized in high yields. Gratifyingly, DMSO plays a dual role as a solvent and a C1 source and can also be replaced with its deuterated

  本研究报告了一种用于合成对称和不对称二芳基甲烷 (DAM) 的温和有效的合成方案。使用 DMSO 作为 C 1源和 TMSOTf 作为路易斯酸促进剂，以高产率合成了一系列功能化的对称和非对称 DAM。令人欣慰的是，DMSO 作为溶剂和 C 1源具有双重作用，并且还可以用其氘代对应物 DMSO- d 6代替，从而能够掺入 -CD 2部分进入二芳基甲烷骨架。所开发的方法已应用于具有各种官能团的各种底物，该协议也已扩展到使用普通原料化合物合成抗乳腺癌剂和抗凝剂。此外，已通过对照实验明确证明了假设的机制。
