Abstract A systematic study has been conducted on a novel luminescent metal-organicframework, [Zn(bpyp)( L -OH)]·DMF·2H2O}n (1), to explore its sensing mechanisms to Fe3+. Structure analyses show that compound 1 exist pyridine N atoms and -OH groups on the poresurface for specific sensing of metal ions via Lewis acid-base interactions. On this consideration, the quenching mechanisms are studied
To provide an electrochromic compound represented by the following general formula (1) where X1 and X2 are each independently a carbon atom or a nitrogen atom, R1, R2 and R3 are each independently a halogen atom, a substituted or unsubstituted alkyl group, or a substituted or unsubstituted alkoxy group, x is an integer selected from 0 through 3, y and z are each independently an integer selected from 0 through 4, and at least one of L1 and L2 is a monovalent functional group bonded to a nitrogen atom of a pyridinium ring directly, or via a divalent substituent.

rocking-chair-type "molecular ion battery" in which a molecular ion, instead of Li+ , works as a charge carrier. Previously, we reported a viologen-type derivative as a negative electrode material that releases and receives PF6 - anions during the charge-discharge process; however, its redox potential was not satisfactorily low. Further, the two potential plateaus of this material (difference=0.5 V)
已经提出了许多类型的电池作为下一代能量存储系统。一种候选者是摇椅型“分子离子电池”,其中分子离子代替Li +充当电荷载体。以前,我们报道了一种紫精型衍生物作为负极材料,该材料在充电和放电过程中会释放并接受PF6-阴离子。然而,其氧化还原电势并不令人满意。此外,应减小该材料的两个电位平台(差= 0.5 V)。在该研究中,合成了由芳香环延伸的紫罗兰(联吡啶鎓)衍生物的PF6-盐,得到的负极材料在充放电过程中氧化还原电位较低,电位变化较小。某些合成的紫精衍生物即使在固态电极中也具有荧光。在半电池构造中,所制备的负极材料显示出约2 V(vs. Li + / Li)的平均电压,低于常规的紫精衍生物的平均电压。
