Cong, Zhenxing published the artcileHighly efficient crystal red fluorescent 1,2-squaraine dyes with excellent biocompatibility and bioimaging, HPLC of Formula: 606-55-3, the publication is Dyes and Pigments (2019), 654-661, database is CAplus.

A new family of asym. 1,2-squaraine dyes (1,2-SQs) were designed and synthesized in high yields. The photophys. anal. presented that these 1,2-SQs showed strong red fluorescence in crystal state but weak fluorescence in solution, suggesting their aggregation-induced emission enhancement (AIEE) properties. Single crystals X-ray diffraction revealed that the intense fluorescence in the crystal state can be attributed to the effects of long alkyl chains or large group substituents in the mols., which efficiently prevented the tight intermol. contact and reduced π-π interactions. The biocompatibility and cell imaging applications of SQ4 were further investigated. The results demonstrated that SMMC-7721 cell can be clearly imaged by SQ4, which inferred SQ4 had excellent biocompatibility and potential value for bioimaging.

Wu, Zhaofan published the artcileResolving variable cell viability-induced false negative: Accurate and high-contrast fluorescence diagnosis of cancer enabled by dual organelle targeting and multiple microenvironmental parameters responsive versatile carbon dots, Formula: C12H14IN, the publication is Sensors and Actuators, B: Chemical (2022), 131577, database is CAplus.

Developing effective fluorescence-based diagnostic methods for cancer is of great importance but remains a major challenge owing to the low contrast and limited accuracy induced by the variable cell viability. To increase contrast and accuracy in cancer diagnosis, a dual-organelle-targeting and multiple-parameter-responsive design strategy is proposed here. As a proof of concept, versatile carbon dots (CDs) targeting mitochondria and nucleoli with ability to respond to three environmental parameters (mitochondrial membrane potential, viscosity, and RNA) are developed. These capabilities not only enable high-contrast and accurate imaging of cancer cells but also make the CDs highly robust against interference from environmental parameters alterations induced by cell damage or apoptosis. This new design strategy involving targeting of multiple organelles and multiple responsiveness to environmental parameters could inspire further research in bioactive material-based cancer imaging.

Tian, Tao published the artcileMolecular full-adder and full-subtractor logic circuit based on fluorescein derivatives, COA of Formula: C12H14IN, the publication is Gaodeng Xuexiao Huaxue Xuebao (2015), 36(2), 260-266, database is CAplus.

Over the past decade, there has been significant progress in the development of mol. computer, which has inspired scientists to construct appropriate mol. systems that could integrate simple logic gates into combinatorial circuits. In this work, a novel fluorescein-based QHF⁺ with five-state mol. switch was synthesized. The conversion of the five states of QHF⁺ was observed by UV-visible absorption spectra under various pH values in CH₃CH₂OH/H₂O (volume ratio 1:1). Spectral responses with the use of chem. inputs in the form of H⁺ and OH^– revealed that QHF could function as a combinatorial logic circuit (XOR gate and INHIBIT gate, AND gate and XOR gate). Absorbance change at 424 and 490 nm or transmittance change at 424 nm, was monitored as output signals with threshold value of A=0.209 (or T=61.8%). When absorbance intensity or transmittance percentage was more than the threshold value, the output signal was 1. Otherwise, the output value was 0. In conclusion, a full-subtractor was achieved by setting the initial state to QHF⁰ with outputs at 424 and 490 nm in the absorption mode, while a mol. full-adder was provided by setting the initial state to QHF⁺ and observing both absorbance at 490 nm and transmittance at 424 nm.

Wang, Qing published the artcileNovel water soluble styrylquinolinium boronic acid as a ratiometric reagent for the rapid detection of hypochlorite ion, Application of 1-Ethyl-2-methylquinolin-1-ium iodide, the publication is Dyes and Pigments (2013), 99(3), 733-739, database is CAplus.

A novel water soluble styrylquinolinium boronic acid (I) was synthesized in good yield. A selective oxidation of the C-B bond of the dye by hypochlorite was observed During the oxidation of the dye, the replacement of the strong electron-withdrawing group (-BOH₂) by the electron-donating group (-OH) on the fluorophore resulted in a large red shift of the absorption and emission spectra due to the intramol. charge-transfer process. Based on the oxidation induced intramol. charge-transfer mechanism, the application of the dye as a ratiometric optical chemosensor for ClO^– was studied. It exhibited high selectivity for ClO^– anions over other relevant metal ions, anions and highly reactive oxygen species. Meanwhile, the fast oxidation event along with the characterized color changes allowed the dye to be developed as selective visual chemosensor for ClO^–.

Budyka, Mikhail F. published the artcileProton-driven “one-way” photoisomerization due to energy transfer switching in styrylquinoline-merocyanine dyad, Related Products of iodides-buliding-blocks, the publication is Journal of Photochemistry and Photobiology, A: Chemistry (2014), 59-64, database is CAplus.

Photophys. and photochem. properties of the novel bichromophoric covalently linked dyad SQ3MC, where 2-styrylquinoline (SQ) and merocyanine (MC) chromophoric groups are connected by dioxytrimethylene bridge O-(CH₂)₃O, in comparison with model compounds 2-(4-methoxystyryl)quinoline MeSQ and 1-ethyl-2-(4-methoxystyryl)quinolinium perchlorate, which is O-methylated merocyanine MeMC, are investigated. In dyad SQ3MC, trans → cis photoisomerization of SQ moiety is quenched because of competing Forster resonance energy transfer (FRET) to MC fragment. However, reaction is switched on in protonated quasisym. dyad where pos. charged SQ fragment obtains the same chromophoric π-system as in MC chromophore. After deprotonation, photoisomerization of SQ fragment in trans → cis direction is again switched off but goes in cis → trans direction. Effect of “one-way” photoisomerization in the dyad SQ3MC is kinetic in nature and based on the difference in rates of competing processes in the excited state, in contrast to well-known one-way reactivity of diarylethylenes with large aryl substituents, where effect is thermodn. in nature and based on the difference in energies of the excited-state isomers and conformers.
