ALKYNES PROTECT SEMICONDUCTING ACENES FROM OXYGEN DAMAGE

摘要

Acenes-oligomers of fused benzene rings-such as anthracenes (three rings), tetracenes (four rings), and pentacenes (five rings) are useful organic semiconductors and luminescent sensors. These materials are notorious for their high reactivity with oxygen, which can be essential to using them as luminous oxygen sensors; however, this same reaction also destroys their semiconducting properties.
