A conjugated ladder polymer composed of negatively curved cyclooctatetraene monomer units was synthesized in a single step from bis-zirconacyclopentadienes, resulting in microporosity and high processability.
A synthetic sequence leading to the controlled decoration of cyclopentadienes is reported. This approach allows site-selective installation of different functionalities around the Cp ring, exploiting stereoelectronic features of internal alkynes.
Tellurophene, a five-membered heterocycle of metalloid tellurium, has unique redox, and optoelectronic properties. When integrated as a homopolymer or copolymer, these polymers exhibit novel properties, tailorable towards various applications.
Functional organoarsenic chemistry has advanced remarkably in the past decade. This review highlights the pivotal synthetic strategies that initiated this growth and surveys the wide range of developments that have since emerged.
Researchers have used the relative instability of azides and alkynes to access reactive intermediates that would be otherwise difficult to obtain. These processes, reviewed herein, have yielded a wealth of unique reactivity and valuable structures.
