The cover picture shows that benzene/2,2′-bipyridine-alternately incorporated amide polymers are driven by hydrophobicity to form two helical conformations both of which exhibit helicity bias. Switching between the two helical conformations can be tuned by the coordination of the 2,2′-bipyridine units to Ni2+ ions. More details are discussed in the article by Li et al. on page 678–682.

Voltammetric reduction of a series of 1,4-dimethoxypillar[m]arene[n]quinones (DMP[m]A[n]Qs) has been studied on glassy carbon electrode in acetonitrile. All the quinone units showed relative electron uptake behavior except 1,4-dimethoxypillarquinones (DMPQs). The electrochemical behavior of the systems being investigated was obviously different when compared with linear analogues of quinones systems. This is attributed to the close proximity of redox-active sites as well as the delocalization of electrons on the aromatic rings.
- Facile Synthesis of Naphtho[2,3-d]thiazoles, Naphtho[2,3-e][1,3,4]thiadiazines and Bis(naphtho[2,3-d]thiazolyl)copper(II) Derivatives from Heteroylthiosemicarbazides

A one step synthesis protocol for the conversion of heteroylthiosemicarbazides and 2,3-dichloro-1,4-naphthoquinone to naphtho[2,3-d]thiazoles, naphtho[2,3-e][1,3,4]thiadiazines as well as bis(naphtho[2,3-d]thiazolyl)copper(II) derivatives via Eschenmoser coupling reaction is described. The products were conclusively confirmed by single crystal X-ray analyses. A mechanism for the formation of the products is presented.
