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

Dual Side Chain Functionalization of Small Molecule Acceptors Affords High‐Performance Organic Solar Cells With Refined Blend Morphology

open access: yesAdvanced Functional Materials, EarlyView.
A new small‐molecule acceptor (SMA‐Ph‐CF3) is developed using a dual side chain functionalization strategy that incorporates trifluoromethyl and phenyl groups. This approach enables precise tuning of blend morphology, leading to the fabrication of high‐performance organic solar cells with a power conversion efficiency of 18.5%.

1D Light‐Emitting MAPbBr3 Perovskite Encapsulated in Carbon Nanotubes

open access: yesAdvanced Functional Materials, EarlyView.
Encapsulation of MAPbBr3 perovskite in single‐walled carbon nanotubes (SWCNTs) yields a hybrid nanomaterial with distinctive optoelectronic properties. Perovskite confinement induces a unified single‐peak photoluminescence (PL) with a reduced lifetime, while charge transfer alters the optical properties of nanotubes.
