Pore Nanoarchitectonics of Carbon Nitrides for the Excited‐State Deactivation of Confined Methylene Blue

The relaxation dynamics in excited states of methylene blue dyes adsorbed on porous carbon nitrides were investigated by ultrafast transient absorption spectroscopy. Such space confinement results in accelerated excited-state relaxation of dyes showing distinct excited-state properties by intermolecular electronic interactions. The confinement effect described by B. Dietzek-Ivanšić, M. Oschatz, and co-workers in their Research Article extends our understanding of the use of nanoarchitectonics to modulate excited state properties of photoactive molecules.
