The present invention addresses the problem of providing a novel alkoxymethyl-substituted bisphenol compound having exceptional storage stability and exceptional solvent solubility, heat resistance, and optical properties when used as a resin raw material. This problem can be solved by using an alkoxymethyl-substituted bisphenol compound represented by General Formula (1):
(wherein each R independently represents an alkyl group having 1 to 4 carbon atoms).
本发明所要解决的问题是提供一种新型的烷氧基甲基取代双酚化合物,该化合物在用作树脂原料时具有优异的贮存稳定性和优异的溶剂溶解性、耐热性和光学性能。使用通式(1)表示的烷氧基甲基取代双酚化合物可以解决这个问题:
(其中每个 R 独立地代表一个具有 1 至 4 个碳原子的烷基)。

Phenol quaternary ammonium derivatives: charge and linker effect on their DNA photo-inducible cross-linking abilities
We report here that phenol derivatives with two and four quaternary ammoniums were synthesized and their abilities to bind and cross-link DNA were investigated. Thermal denaturizing studies indicated that derivatives possess similar DNA binding abilities and gel electrophoresis revealed that more charges (series B) and electronic donation substitute linkers (like –S–) dramatically increase the DNA cross-linking abilities.
我们在此报告合成了含有两个和四个季铵的苯酚衍生物,并研究了它们与 DNA 结合和交联的能力。热变性研究表明,这些衍生物具有相似的 DNA 结合能力,凝胶电泳显示,更多的电荷(B 系列)和电子捐赠替代连接体(如 -S-)可显著提高 DNA 交联能力。
