摘要: Functional organic materials with enhanced two-photon absorption lead to new technologies in the fields of chemistry, biology, and photonics. In this article we review experimental theoretical methodologies allowing detailed investigation analysis properties chromophores. This includes femtosecond excited fluorescence setups quantum-chemical based on time-dependent density functional theory. We thoroughly analyze physical phenomena trends leading large twophoton responses a few series model chromophores focusing effects symmetric asymmetric donor/acceptor substitution branching.
