Few concepts are as frequently used as aromaticity in the current chemical literature. 1 This
may be quantified by ca. 300 000 papers dealing with the aromatic properties of chemical …

Organic π-conjugated polymers and oligomers (Chart 1) are intriguing compounds that have
been intensively studied for almost 30 years by now. 1-3 The interest in these systems is …

Lithium salts enlisting azide, oxocarbons, dicarboxylates and hydrazides have been
identified as a practical mean to compensate the irreversible capacity loss of LIBs negative …

Zinc trifluoromethanesulfonate promotes efficient condensations of anilines with squarate
esters, providing access to symmetrical and unsymmetrical squaramides in high yields from …

Over the last 15 years, squaramide-based receptors have attracted the attention of
supramolecular chemists working in the field of anion recognition. Herein, we highlight …

Squaramides represent a class of vinylogous amides that are derived from the squarate
oxocarbon dianion. While they have been known since the 1950s, squaramides have only …

π-Conjugated organophosphorus derivatives have recently emerged as valuable building
blocks for the tailoring of functional molecular materials. We have focused for ten years on …

Secondary squaramides have considerable potential as hydrogen bond donors and
acceptors. In CHCl3 both, anti-and syn-squaramide rotamers are observed by NMR. The …

The acetylene unit has long been regarded as just a useful functional tool in synthetic
organic chemistry. Over the last 30 years however, it also gained the status of a peculiar …

This review provides an overview of phosphole-based ligand families (monophospholes,
multidentate hybrid phosphole ligands, diphospholes and 2, 2′-biphosphole-based …
