PCBM-based n-type semiconductors - Find p- and n-type organic semiconductors available with PCBM library & properties.

The development of high-performance conjugated organic molecules and polymers has received widespread attention in industrial and academic research.

Mesoporous materials are formed by a self-assembly process from combined solutions of sol-gel precursors (e.g., metal alkoxides) and structure-directing amphiphiles, usually block-copolymers or surfactants.

In this article, we demonstrate that bis-styrylbenzene derivatives show promising characteristics for very low lasing thresholds and discuss the design considerations for organic lasing molecules.
