Cationic fac-[Re(CO)(3)(pz*H)(pypzH)]OTf (pz*H = pyrazole, pzH; 3,5-dimethylpyrazole, dmpzH; indazole, indzH; 3-(2-pyridyl)pyrazole, pypzH) were obtained from fac[ReBr(CO)(3)(pypzH)] by halide abstraction with AgOTf and subsequent addition of the corresponding pyrazole. Successive deprotonation with Na2CO3 and NaOH gave neutral fac[Re(CO)(3)(pz*H)(pypz)] and anionic Na{fac-[Re(CO)(3)(pz*)(pypz)]} complexes, respectively. Cationic fac-[Re(CO)(3)(pz*H)(pypzH)]OTf, neutral complexes fac-[Re(CO)(3)(pz*H)(pypz)], and fac-[Re(CO)(3)(pypz)(2)Na] were subjected to photophysical and electrochemical studies. They exhibit phosphorescent decays from a prevalently (MLCT)-M-3 excited state with quantum yields (F) in the range between 0.03 and 0.58 and long lifetimes (tau from 220 to 869 ns). The electrochemical behavior in Ar atmosphere of cationic and neutral complexes indicates that the oxidation processes assigned to Re-I -> Re-II occurs at lower potentials for the neutral complex compared to cationic complex. The reduction processes occur at the ligands and do not depend on the charge of the complexes. The electrochemical behavior in CO2 saturated media is consistent with CO2 electrocatalyzed reduction, where the values of the catalytic activity [i(cat)(CO2)/i(cat)(Ar)] ranged from 2.7 to 11.5 (compared to 8.1 for fac-[Re(CO)(3)Cl(bipy)] studied as a reference). Controlled potential electrolysis for the pyrazole cationic (3a) and neutral (4a) complexes after 1 h affords CO in faraday yields of 61 and 89%, respectively. These values are higher for indazole complexes and may be related to the acidity of the coordinated pyrazole.

Linear alkanes are essential building blocks for natural and artificial assemblies in water. As compared with typical, linear alkane-based micelles and recent aromatic micelles, we herein develop a cycloalkane-based micelle, consisting of bent amphiphiles with two cyclohexyl frameworks. This uncommon type of micelle, with a spherical core diameter of similar to 2nm, forms in water in a spontaneous and quantitative manner. The cycloalkane-based, hydrophobic cavity displays peculiar host abilities as follows: (i) highly efficient uptake of sterically demanding Zn(II)-tetraphenylporphyrin and rubrene dyes, (ii) selective uptake of substituted Cu(II)-phthalocyanines and spherical nanocarbons, and (iii) uptake-induced solution-state emission of [Au(I)-dimethylpyrazolate](3) in water. These host functions toward the large metal-complex and other guests studied herein remain unaccomplished by previously reported micelles and supramolecular containers.

Ampelocalamus scandens is native to Guizhou Province, China, and grows at an altitude of 260-320 m. It can be used as a raw material for weaving and papermaking. In the current study, the complete chloroplast (cp) genome of A. scandens was sequenced and is reported for the first time. The complete cp sequence was 139,504 bp, include large single-copy (LSC), small single-copy (SSC), and a pair of invert repeats (IR) region of 83,103 bp, 12,813 bp, and 21,793 bp, respectively. Besides, the plastid genome comprised a total of 132 genes, including protein-coding, tRNA, and rRNA genes as 85, 39, and 8 genes, respectively. Phylogenetic analysis based on 28 cp genomes reveals that A. scandens is closely associated with Ampelocalamus melicoideus in Arundinarodae.
