  Water-Soluble Polymeric Photoswitching Dyads Impart Super-Resolution Lysosome Highlighters

  摘要：

  In this report, we integrated a photoswitchable quencher, a highly emissive yet pH sensitive fluorophore, and a water-soluble polymer with controlled hydrophilicity into a functional nanosystem. The photoswitching quencher is based on dithienylethene (DTE) unit, while the pH-sensitive emitter is naphthalimide (NI) unit and the water-soluble polymer is obtained from polymerization of N-isopropylacrylamide (NIPAM). Together, these three units create a novel super-resolution lysosome highlighter, although individually none can function as a lysotracker. Because the emitter is sensitive to pH, the resulting polymer becomes highly fluorescent in acidic lysosomes. In addition, photoswitching regulates the fluorescence on and off and thus enables super-resolution localization of fluorescent polymers with sub-40 nm spatial resolution in imaging subcellular organelles. Thus, the concept presented here, including the photoswitchable DTE-pH-sensitive NI dyad, is promising to guide the development of future-generation super-resolution imaging agents.

  通过使用4-哌嗪萘二甲酰亚胺衍生物对光交联的水溶胀性丙烯酸膜进行功能化而获得的固体荧光传感器

  摘要：

  为了进一步官能化，已经制备了基于乙烯基-吡咯烷酮/丙烯酸丁酯的光交联膜（M-Cl），其包含乙二醇二甲基丙烯酸酯作为交联剂和甲基丙烯酰氯作为反应性单体。已经使用两种方法合成了一系列羟基取代的哌嗪萘二甲酰亚胺化合物，作为pH敏感的Off-On荧光探针：微波和回流。通过Schotten-Baumann反应，选择了三种衍生物通过酰氯基团锚定在M-Cl膜上。使用不同的技术对所有获得的水溶胀膜进行表征。研究了光诱导电子转移（PET）及其pH依赖的光学变化，并使用pH依赖的吸收光谱和荧光光谱确定了各种光化学参数。在9.0-4.0的pH范围内，这些固体传感器经历了从哌嗪到萘二甲酰亚胺部分的PET处理，从而导致了荧光猝灭。但是，在4.0-1.0的pH范围内，PET被抑制以增强荧光。功能化膜对pH变化的敏感性取决于萘二甲酰亚胺取代基的大小和位置。

  We attribute these differences due to different spacers used to link the ferrocenyl unit and the naphthalimide moiety. Measurements of the fluorescence spectrum and the fluorescence lifetime confirmed that the fluorescence of the naphthalimide is strongly quenched by the effective PET from the ferrocenyl units to the naphthalimide moieties. The PET path in 6-[4-(2-oxo-2-ferrocenyl-ethyl)-piperazin-1

  已经合成了包含连接在萘二甲酰亚胺环的4-位上的4-氨基-1，8-萘二甲酰亚胺的二茂铁衍生物。电化学数据和电荷分离的自由能（ΔGcs）表明，从二茂铁单元到萘二甲酰亚胺部分的光诱导电子转移（PET）对于这些二茂铁衍生物在热力学上是可行的。它们的吸收光谱表明，对于这些二茂铁衍生物，二茂铁基单元与萘二甲酰亚胺部分之间的电子相互作用非常不同。我们将这些差异归因于用于连接二茂铁基单元和萘二甲酰亚胺部分的不同间隔基。荧光光谱和荧光寿命的测量证实，萘二甲酰亚胺的荧光被有效的PET从二茂铁基单元至萘二甲酰亚胺部分强烈淬灭。6- [4-（2-氧代-2-二茂铁基-乙基）-哌嗪-1-基]-苯并[DE ]异喹啉-1,3-二酮可通过二茂铁单元的两个氧化和烷基化的胺基团的质子化被关闭。这些类型的二元组可以用作双模式化学（质子）/电致变色分子开关。

  Two novel polymers with naphthalimide pendant groups have been prepared. In poly(2-methylacrylic acid 2-[6-(4-methylpiperazin-1-yl)-1,3-dioxo-2,3-dihydro-1H-benzo[de]isoquinolin-2-yl]ethyl ester-co-methyl methacrylate) (copolymer 1), an alkylated tertiary amine acts as an electron donor and quenches the fluorescence of the naphthalimide fluorophore via the photo-induced electron transfer (PET) process. Protonation of the alkylated tertiary amine by an acid generated by a photoacid generator (PAG) can switch off the PET path and the fluorescence of the naphthalimide fluorophore would be recovered and enhanced. For poly(2-methylacrylic acid 2-[6-(4-methylpiperazin-1-yl)-1,3-dioxo-2,3-dihydro-1H-benzo[de]isoquinolin-2-yl]ethyl ester) (polymer 3), protonation both of the aromatic amine and the alkylated amine by the acids generated from may result in significant fluorescence quenching and alter the fluorophore. When protonation processes occur, the fluorescence enhancement (×2) of copolymer 1 or the fluorescence quenching (×15) of polymer 3 would be applied to generate positive or negative fluorescent patterned images on their net films.
