What is it about?
The energy difference between the ground and excited states of a molecule could be tuned through modulation of the intramolecular charge transfer (ICT) process that could affect its linear and nonlinear optical (NLO) response. NLO processes such as second harmonic generation, sum-frequency generation and two-photon absorption have been used extensively for numerous technological applications. Recently, through-bond and through-space ICT have been employed to tune the reverse intersystem crossing for fabricating next generation organic light-emitting diodes. In this perspective, the state of the art and challenges in designing ICT-based molecules and materials for optical applications have been discussed.
