A single fluorescent probe herein can sensitively and selectively detect H2S and NO in solution and in cells by using a logic gate approach.
这里的单一荧光探针可以通过逻辑门方法在溶液和细胞中敏感且选择性地检测H2S和NO。
Trichromatic-emission and dual-ratio semiconducting polymer dots as fluorescent probe for simultaneous quantification of Cu<sup>2+</sup> and pH <i>in vitro</i> and <i>in vivo</i>
Novel dual-ratio semiconducting polymer dots (Pdots) with trichromatic-emission in the red, green and blue primary-color regions, are designed as lysosome-targeting nanoprobes for the simultaneous detection and multicolor imaging of pH and Cu2+ in HeLa cells and zebrafish without cross-interference.
To investigate the asymmetric effect of the naphthalimidemoiety on the thermal, mechanical, optical properties and water uptake of polyimides (PIs), two novelasymmetric diamines, 4-(4-aminophenoxy)-N-amino-1,8-naphthalimide 3 and 4-(4-aminophenoxy)-N-(4-aminophenyl)-1,8-naphthalimide 4 were synthesized. Two series of PIs 5b–e and 6a–e were prepared from diamines 3 and 4 by solution polymerization
We report herein DABCO mediated one pot synthesis of 2‐(3‐benzyl‐2, 6‐dioxo‐3,6‐dihydropyrimidin‐1[2H]‐yl)‐N‐(4‐(1,3‐dioxo‐1H‐benzo[de]isoquinolin‐2[3H]‐yl) aryl) acetamides (4a‐j). The silent features of this new one pot synthesis include the shorter reaction time, high yields, simple workup, and simultaneous formation of N‐Amide and N‐benzyl bonds in the one pot. The newly synthesized compounds (4a‐j)
growth into crystals rather than one‐dimensional gel nanofibers. Water binding was also reflected on the supramolecular chirality inversion of vesicle self‐assembly in aqueous media via heating‐induced dehydration. Structural parameters that favor water binding were evaluated in detail, which could help rationallydesignorganic building units for advancing soft materials, crystal engineering, and chiral
