Synthesis and Molecular Properties of Tricyclic Biselenophene-Based Derivatives with
Nitrogen, Silicon, Germanium, Vinylidene, and Ethylene Bridges.
Org. Lett. 2014;
16: 5724-5727
Key words
divergent synthesis - biselenophenes
Significance
While tricyclic bithiophene-based materials have been extensively studied as an important
class of organic semiconductors, the corresponding biselenophene-based analogues have
not been reported. Cheng and co-workers demonstrate for the first time that biselenophene
1 can be utilized as starting material for the synthesis of a new class of both sp3-bridged and sp2-bridged tricyclic biselenophene-based materials.
Comment
The six brominated molecules highlighted above can be used as monomers to create a
new class of p- or n-type polymers for exploring biselenophene-based materials in
various optoelectronic applications, such as organic field-effect transistors and
polymer solar cells.
