One of the most important objectives in materials, chemical, and physical sciences is the
creation of large conjugated macrocycles with well‐defined shapes, since such molecules …

Taken to the molecular level, the concept of “tweezers” opens a rich and fascinating field at
the convergence of molecular recognition, biomimetic chemistry and nanomachines …

We have designed and synthesized a π-conjugated system that consists of a flexible and
nonplanar π joint and two emissive rigid and planar wings. This molecular system exhibits …

The hybridization of flexible and rigid π‐conjugated frameworks is a potent concept for
producing new functional materials. In this article, a series of multifluorescent flap** π …

Rh COT in the act: a Ni (0)-catalyzed [2+ 2+ 2+ 2] cycloaddition provides a high-yielding,
scalable synthesis of the ligand dinaphtho [a, e] cyclooctatetraene (dnCOT). dnCOT …

ACHTUNGTRENNUNGecules,[1e–f, 4, 5] have attracted considerable attention from organic
chemists because they are both synthetically interesting and have unique properties, like …

Schneller Wechsel: In cyclischen Thiazoltetrameren, die flexiblen Cyclooctatetraenen mit
erweitertem π‐System entsprechen (siehe Bild), führen die Kopf‐Schwanz‐angeordneten …

Overcrowded ethylenes composed of 10‐methyleneanthrone and two bulky aromatic rings
contain a twisted carbon–carbon double (C= C) bond as well as a folded anthrone unit. As …

A facile one-pot tetramerization of indolin-2-one with phosphoryl chloride was applied for the
first convenient direct synthesis of C 2 v-symmetric cyclooctatetraindole with an 8π annulene …

Substances containing two π‐congested aromatic systems are attractive targets in synthetic
studies as well as efforts designed to explore the unique properties that originate from π …
