Acene is a type of organic compound that belongs to the family of polycyclic aromatic hydrocarbons (PAHs). It consists of a linear arrangement of several fused benzene rings, with the number of rings increasing with the length of the acene molecule. Acenes are important materials in organic electronics due to their unique optoelectronic properties, such as high carrier mobility, high photoluminescence quantum yield, and tunable energy levels. They have potential applications in various electronic devices, including organic field-effect transistors, organic light-emitting diodes, and organic solar cells. The most well-known acene is naphthalene, which consists of two fused benzene rings. Other examples of acenes include anthracene (three fused benzene rings), tetracene (four fused benzene rings), and pentacene (five fused benzene rings).
