The formation of a single-molecule-like aggregate (SMA) represents a remarkable phase where organic emitters are held closely yet remain electronically isolated, achieving a near-unity photoluminescence quantum yield comparable to single molecules.
Molecular dynamics simulations reveal that the internal rotational and vibrational degrees of freedom of the molecules within the two-dimensional superlattice are crucial for developing the exclusive SMA phase.
This innovative approach harnesses the benefits of both single molecules and aggregates, paving the way for advanced spectroscopic and photonic applications, including enhanced radiative recombination and efficient lasing.
By utilizing a two-dimensional hybrid perovskite superlattice, we can achieve robust directional emission and improved optoelectronic properties, addressing a long-standing knowledge gap in organic luminescent technologies.
