Regulation of a conjugate rigid plane structure based on bisbenzimidazole derivatives to research the structure-effective relationship between conjugate systems size and fluorescence sensing properties.

Metallogel-based six membered sensor arrays show applications in multi-analyte detection and fluorescence encryption.

Supramolecular xerogel films as multicolor photoluminescent materials are ideal for applications in optical devices, such as photochromic smart windows and LEDs. Therefore, a blue-fluorescence supr...

Herein, by rationally introducing multi-interactions sites, a new rhodamine derivative BT was successfully designed and constructed. The BT can further self-assemble into a stable supramolecular organogel BTG and exhibits strong pink-white aggregation-induced emission (AIE). Interestingly, the BTG exhibits selective and ultrasensitive sensing property for Cu2+. The limit of lowest detection (LOD) of BTG for Cu2+ is approximately 0.829 nM. By adding Cu2+ into the BTG, a no fluorescence Cu2+ coordinated metallogel BTG-Cu formed. Due to the competitive coordination of Hg2+, the BTG-Cu exhibits promising sensing properties for Hg2+, such as high selectivity and ultra-sensitivity, fluorescence turn-on response, instant response to Hg2+ (

The selective and ultrasensitive detection of H2PO4−, critical component of biomolecules and key substrates for many biochemical reactions, is extremely important. Herein, a signal amplification strategy was successfully used by introducing metal ions into pillar[5]arene-based supramolecular gel (TB). Accordingly, the in-suit generated non-fluorescent metal coordinated supramolecular gel (TB-Fe) could serve as a fluorescence “turn-on” sensor to detect H2PO4− selectively and ultrasensitively, and the limit of detection (LOD) of TB-Fe for H2PO4− was calculated to be 2.82 nM.

Objective To clarify the rationality and to provide reasonable usage references of processed Corydalis Rhizoma (CR) in clinic by comparing respectively pharmacological actions including analgesic, anti-inflammation, antiplatelet aggregation and spasmolysis of Yuanhu Zhitong Tablet (YZT) and Yanhusuo Decoction (YD) constituted with raw CR (RCR) or processed CR (PCR). Methods The hot-board, acetic-acid-induced twisting experiments and mouse auricular swelling model by injecting xylene in the abdomen of mouse were adopted to investigate the analgesic and anti-inflammatory effects of the four formulas on Kunming mice; The experiment of contractile activity on isolated rat intestine smooth muscle on Wistar rats was applied to observing the spasmolysis effect of the four formulas; The experiments of platelet aggregation induced by ADP or collagen on Wistar rats by turbidimetry method were used to observe the anti-platelet aggregation effect of the four formulas. Results Compared with RCR in two prescriptions, PCR displayed better analgesic effect (P Conclusion PCR can improve the analgesic effect of prescription YZT and intensify the spasmolysis effect of prescription YD, which can be explained by the Chinese medicine processing regulation. Therefore, PCR is suggested to be chosen in YZT and YD used to cure pain symptoms.
