π-Bridge-Driven Design of Donor-π-Acceptor Organic Crystals for Stable, Long-Wavelength Near-Infrared Nanolasers
The development of near-infrared (NIR) organic lasers has long been constrained by inefficient excited-state intramolecular proton transfer (ESIPT) and limited electronic delocalization, which restrict both performance and scalability. In this study, we demonstrate that subtle molecular modifications can improve lase...
