Frontiers of Chemical Science and Engineering 2015, Volume 9, Issue 4,   Pages 488-493 doi: 10.1007/s11705-015-1503-9

Abstract: A series of -alkoxylbenzamides featuring a long alkyl chain have been synthesized and are readily to form stable gels in a variety of organic solvents. Their self-assembly properties and structure-property relationship were investigated by scanning electron microscopy, X-ray diffraction, H nuclear magnetic resonance, and Fourier transform infrared spectroscopy. The gels formed were multi-responsive to environmental stimuli such as temperature and fluoride anion. The results show that a combination of hydrogen bonding, π-π stacking and van der Waals interaction result in the aggregation of -alkoxylbenzamides to form three-dimension networks, depending on the length of the long alkyl chain.

2,5-Dialkoxylphenyl-1,3,4-oxadiazoles as efficient organogelators and their self-assembling property

Zipei SUN,Xuelin DONG,Yan ZHAI,Ziyan Li,Yaodong HUANG

Frontiers of Chemical Science and Engineering 2014, Volume 8, Issue 2,   Pages 219-224 doi: 10.1007/s11705-014-1418-x

Abstract: Four 2,5-dialkoxylphenyl-1,3,4-oxadiazoles are shown to be efficient organogelators. These compounds readily form stable gels in many organic solvents and their gelation property as well as supramolecular structures were investigated by scanning electron microscopy (SEM), X-ray diffraction (XRD), H nuclear magnetic resonance ( H NMR), and ultraviolet-visible spectroscopy (UV-vis). The results indicate that the gelator molecules self-assemble into gels with elongated fibrous networks and layer structures, and van der Waals interaction is the main driving force.

Synthesis and ultraviolet/aggregation-induced emission investigation of novel tetraphenylvinyl hydrazone derivatives: efficient multimodal chemosensors for fluoride ion

Frontiers of Chemical Science and Engineering 2023, Volume 17, Issue 12,   Pages 2061-2073 doi: 10.1007/s11705-023-2366-0

Abstract: Herein, three novel tetraphenylethylene hydrazone chemosensors TC12, SC16, and TC16 are prepared for the selective detection of F−. Two NH and one C=N units are incorporated into the sensors for better colorimetric responses, whereas the tetraphenyl unit is in charge of the aggregation-induced emission effect. Among them, compounds SC16 and TC16 form stable gels with some organic solvents. All the tetrahydrofuran/H2O solutions of the three compounds exhibit aggregation-induced emission effect, whereby the fluorescence emission increases by varying degrees with the volume of poor solvent water. Moreover, good aggregation-induced emission effects are observed in the self-assembly of SC16 and TC16. As a sample chemosensor, TC12 in tetrahydrofuran responds to F− selectively with high sensitivity, with the colorimetric and fluorometric detection limits of 8.25 × 10−7 mol·L–1 and 2.69 × 10−7 mol·L–1, respectively. The reversible gel-sol-gel phase transition and color changes indicate that both SC16-dimethyl sulfoxide and TC16-ethyl acetate gels specifically respond to F– with good sensitivity. The detection results are well supported by ultraviolet-visible spectroscopy, fluorescent spectroscopy, and 1H nuclear magnetic resonance. More importantly, the driving forces of gelation are visually clarified through the single crystal X-ray analysis of compound TOMe.

Novel 1,2,3-triazole-based compounds: Iodo effect on their gelation behavior and cation response

Yaodong Huang, Shuxue Liu, Zhuofeng Xie, Zipei Sun, Wei Chai, Wei Jiang

Frontiers of Chemical Science and Engineering 2018, Volume 12, Issue 2,   Pages 252-261 doi: 10.1007/s11705-017-1683-6

Abstract: Two new series of 1,2,3-triazole derivatives, with and without iodo substitution, were synthesized and their gelation properties were measured. It was found that the iodo substitution at position 5 of triazole ring could greatly enhance the gelation ability. Scanning electron microscopy and X-ray diffraction reveal that the structures of the organogels from iodo and hydrogenous gelators are totally different. Iodo gels are selectively responsive to the stimuli of Hg , whereas hydrogenous gels can respond to Hg and Cu . Moreover, the reversible gel-sol transition of hydrogenous gels can be controlled by redox reaction or tuned with suitable chemicals. The single crystal analysis of reference compound ( ) suggests that there are intermolecular and intramolecular non-classical hydrogen bonding interactions but no π-π interaction in hydrogenous gelator. The great difference between the two series of compounds results from the iodo effect and implies the existence of halogen bonding interaction in the iodo compounds.
