Photo-generated nitric oxide radicals (NO˙) derived from sodium nitroprusside dihydrate (SNP) are employed for the construction of supramolecular hydrogels based on an amino acid derivative precursor, N-fluorenylmethyloxycarbonyl tyrosine phosphate (FYP), which through dephosphorylation produces the gelator, N-fluorenylmethyloxycarbonyl tyrosine (FY). Self-assembly of the amphiphilic gelator yields high-aspect ratio nanofilaments that entangle to form self-supporting, viscoelastic hydrogels. The presence of photolyzed SNP yields periodically twisted nanofilaments with opposite chirality to filaments formed through conventional hydrogelation routes.

利用光生一氧化氮自由基构建超分子水凝胶

源自二水合硝普钠(SNP)的光生一氧化氮自由基(NO˙)用于构建基于氨基酸衍生物前体N-芴基甲氧基羰基酪氨酸磷酸(FYP)的超分子水凝胶,该凝胶通过脱磷酸作用生成胶凝剂,N-甲氧羰基酪氨酸(FY)。两亲性胶凝剂的自组装产生高纵横比的纳米丝,它们缠结在一起形成自支撑的粘弹性水凝胶。光解SNP的存在产生周期性扭曲的纳米丝,其具有与通过常规水凝胶化途径形成的细丝相反的手性。
