Ultrafast Energy Transfer Induced Lasing From a Coplanar Donor‐Acceptor‐Donor Molecule in a Microspherical Cavity

open access: yesAdvanced Functional Materials, EarlyView.
This study presents a novel donor‐bridge‐acceptor‐bridge‐donor (D‐B‐A‐B‐D) molecular system, which shows near‐unity intramolecular excitation energy transfer (IET) from two identical energy donors to a coplanar acceptor. It enables a four‐level energy system for efficient lasing at the acceptor emission band in a microspherical cavity with a low lasing
