Strong Two-Photon Absorption of Singlet Diradical Hydrocarbons

摘要

Two-photon absorption (TPA) of organic materials has attracted considerable attention owing to its growing application in various fields, such as photonics and nanotechnology. Nowadays, TPA can be induced readily by using high-intensity laser pulses. Nevertheless, it is still important to explore molecules that exhibit intense TPA as this may open new pathways into its use and broaden existing TPA applications.
