本文以紫甘蓝蔬菜为原料，进行了pH、金属离子和各种食品添加剂等一系列稳定性分析，探索紫甘蓝色素的最佳存储和使用环境。研究表明，紫甘蓝色素对pH敏感，随着pH增大，色素保留率逐渐减小;不同金属离子对紫甘蓝色素的稳定性也有影响，Fe³⁺会破坏紫甘蓝色素的结构，降低稳定性，保留率仅为8.68%;而Ca²⁺能提高其稳定性。添加剂蔗糖也可提高其稳定性，其中20 g·L^-1的蔗糖水溶液可将保留率提升至119.48%;而食盐、苯甲酸钠和山梨酸钾均会降低其稳定性。

荧光碳点(CDs)已经广泛应用于生物体外/体内的荧光成像。然而，荧光CDs作为生物标记的特异性较差、而且在红光发射区域荧光量子产率(QY)较低，仍然是亟待解决的关键问题。本研究以天然植物绿萝叶片的乙醇提取液为前驱体，通过溶剂热“一锅”法合成了一种红色荧光碳点(命名为EA-CDs，λ_ex/λ_em = 400 nm/660 nm)。EA-CDs具有小尺寸(平均粒径3.9 nm)、高荧光QY (在乙醇中λ_em = 660 nm，QY = 15.4%)、低毒性(体外/体内)和良好的亲脂性(油水分离系数LogP > 0)，因此适用于体外/体内生物荧光成像和标记。实验结果表明该红光CDs不仅可以用于标记植物细胞膜，而且可以作为斑马鱼体内肠道荧光成像工具，有望成为一种通用型具有高荧光量子产率的生物膜红光染料。此外，本工作也为绿萝等观赏性植物的应用开拓了一种新思路。

以1，1′-二甲基-4，4′-联吡啶(甲基紫精，MV)二氯化物和Keggin型多酸单元合成的晶态材料(MV)₂[HPW^Ⅴ₂W^Ⅵ₁₀O₄₀]·2H₂O为催化剂，在无有机溶剂、室温条件下合成了一系列β-氨基醇类化合物。该催化剂不仅能够高效催化β-氨基醇的合成，而且具有良好的稳定性及可回收性。经过6次循环使用后，催化剂活性未出现明显下降，表明其具有较好的循环利用潜力。与传统方法相比，该反应体系不使用有机溶剂并具有反应条件温和、操作简单、环境友好等优点。

Two new viologen-polyoxometalate hybrid crystalline materials: (MV)₂[HPW₂^ⅤW₁₀^ⅥO₄₀] ·2H₂O (1) and (EV)₂[Mo₈O₂₆] (2) have been synthesized by using the cations of 1, 1'-dimethyl-4, 4'-bipyridinium dichloride (methyl viologen, MV) and 1, 1'-diethyl-4, 4'-bipyridinium dibromide (ethyl viologen, EV) as the electron acceptors, and the electron-rich polyoxometalate anions as the electron donors. The structures of compounds 1 and 2 have been determined by single-crystal X-ray crystallography. Hydrogen bond interactions exist between the cations and the anions in 1 and 2. Interestingly, 2 has a photochromic performance with a light response time within 1 min. The photochromic mechanism of compound 2 has been investigated by solid-state diffuse reflection, electron paramagnetic resonance and theoretical calculation. 1 and 2 show good catalytic performance in the photocatalytic degradation of several organic dyes (methylene blue, pararosaniline hydrochloride and rhodamine 6G).

Under the condition of solvothermal synthesis, the viologen ligand 1, 1′‐bis(3‐carboxyphenyl)‐(4, 4′‐bipyri‐ dine) dichloride (H₂bcbpy·2Cl) and KI are coordinated with the metal cadmium ions. A case of thermochromic coor‐ dination polymer [Cd(bcbpy)I₂] ·2H₂O (1) was constructed. Complex 1 displays a 1D chain structure and exhibits thermochromic behavior. Under different temperature stimulation, the complex (ground) slowly changed from green to yellow‐green, and with the increase of temperature, the color of complex 1 gradually deepened, and finally became orange‐yellow. Therefore, complex 1 was prepared as a thermochromic film. In addition, we also performed electrochemical tests on complex 1, which showed that the complex is a semiconductor material.
