A Chiral Low-Molecular-Weight Gelator Based on Binaphthalene with Two Urea Moieties: Modulation of the CD Spectrum after Gel Formation

The synthesis and characterization of a new chiral LMWG 1 based on the axially chiral binaphthalene with two urea moieties were described. A transparent gel in cyclohexane with LMWG 1 was obtained and characterized by SEM, XRD and CD techniques. The results of 1H NMR measurement indicated that the intermolecular H-bonds and π−π interaction may be responsible for the gel formation. It was demonstrated that the gel phase could be destroyed by addition of F- due to the disruption of intermolecular H-bonds. After gel formation, modulation of the CD spectrum of 1 was observed

A New Fluorometric Turn-On Detection of l-Lactic Acid Based on the Cascade Enzymatic and Chemical Reactions and the Abnormal Fluorescent Behavior of Silole

By making use of the aggregation-induced emission feature of silole 1 and the cascade reactions among l-lactic acid (LA), lactate oxidase (LOD), and dodecanoic hydrazine (DH), a new fluorometric “turn-on” method is developed for the detection of LA

Photocontrolled Electron Transfer Reaction between a New Dyad, Tetrathiafulvalene−Photochromic Spiropyran, and Ferric Ion

Photocontrolled electron transfer reaction is important not only for understanding the complicated biological processes such as photosynthesis and respiration but also for the design and studies of molecular electronics. This paper presents the synthesis and spectral and electrochemical studies of a new dyad 1 containing an electroactive unit (tetrathiafulvalene, TTF) and a photochromic unit (spiropyran, SP). Spectral studies showed that the redox states of the TTF unit of dyad 1 in the presence of ferric ions were dependent on the photoswitching process of the spiropyran unit upon UV light irradiation. Electrochemical investigations indicated that the oxidation potential of ferrous ion was largely reduced after coordination with MC (the open form of SP). As a result, the electron-transfer reaction from MC·Fe2+ to TTF+•, which act as electron donor and acceptor, respectively, is thermodynamically favorable. Therefore, the electron-transfer reaction between the TTF unit and ferric ion can be photocontrolled in the presence of the SP unit. The present result shows the possibility to design new electron donor−acceptor supramolecules containing spiropyran units to photoregulate the electron-transfer reaction

A New Saccharide Sensor Based on a Tetrathiafulvalene−Anthracene Dyad with a Boronic Acid Group

A new saccharide sensor based on a tetrathiafulvalene−anthracene dyad with a boronic acid group was designed and synthesized. Our study employed the tetrathiafulvalene (TTF) unit as the electron-rich group in the saccharide sensor instead of an amine group, and this new sensor detects fructose with good selectivity

A Low-Molecular-Mass Gelator with an Electroactive Tetrathiafulvalene Group: Tuning the Gel Formation by Charge-Transfer Interaction and Oxidation

A new low-molecular-mass gelator with one TTF and one urea group is described. It was found that the gel formation can be tuned by formation of CT complexes and oxidation

A New ex-TTF-Based Organogelator: Formation of Organogels and Tuning with Fullerene

A new ex-TTF-based organogelator with l-glutamide-derived lipid unit (compound 1) was synthesized and characterized. The resulting transparent organogels can be obtained with several organic solvents such as toluene, DMSO, and ethanol. It is interesting that its gelation ability can be further enhanced by addition of C60. The 1H NMR and absorption spectral studies indicate that the intermolecular interaction between the ex-TTF unit in 1 and C60 may be responsible for this phenomenon. Further studies imply that the assembly structures in the gel phases in the absence and presence of C60 may be different. Additionally, organogels can also be prepared with compound 1 and PCBM, and the corresponding xerogel was used to modify ITO electrode. A stable and rapid photocurrent was generated after exposure of the modified ITO electrode to light. This may provide an alternative way for photocurrent generation with high energy conversion efficiency
