1547 COVER Sunset for silicon? The push toward electronics that are smaller, faster, and more flexible requires either new inorganic and organic materials or new functionality for silicon and new transistor designs. See the special section beginning on page 1595.

Abstract Ubiquitous use of electronic devices has led to an unprecedented increase in related waste as well the worldwide depletion reserves key chemical elements required their manufacturing. The biodegradable and abundant organic (carbon-based) materials can contribute alleviate environmental impact industry. pigment eumelanin is a bio-sourced candidate for environmentally benign (green) elec...

The rhodium-catalyzed synthesis of phenazasilines from readily achievable biarylhydrosilanes is presented. This highly efficient method offers opportunities for preparing π-extended phenazasilines with enhanced optoelectronic properties for device applications in organic electronics.
