Design Concepts for Solution and Solid-State Emitters - A Modern Viewpoint on Classical and Non-Classical Approaches

Alexander Huber et al.

Summary: For a long time, luminescence phenomena were distinguished between isolated molecules and close-packed structures. However, the discovery of dual-state efficient materials has led to the ability to achieve balanced emission regardless of the molecular surroundings. This mini review explores the structural features of solid-state emitters and provides a generalized perspective on design concepts.

Organic Branched Heterostructures with Optical Interconnects for Photonic Barcodes

Yang Su et al.

Summary: In this study, organic branched heterostructures (OBHs) were designed for optical interconnection, achieving precise control including trunk morphologies and branched microwire number. The OBHs exhibit multichannel coupling outputs and excitation position-dependent waveguide characteristics, leading to various outcoupling signals with tunable intensities and emission colors. The optical interconnects are realized through exciton conversion and photon propagation between branch and trunk at the heterojunction, benefiting the application possibilities of two-dimensional (2D) optical barcodes.

Molecular Conformation Engineering To Achieve Longer and Brighter Deep Red/Near-Infrared Emission in Crystalline State

Jianan Dai et al.

Summary: A series of molecules with the same fluorophore and different alkyl chains were synthesized to investigate the effect of molecular conformations on emission properties. The results showed that the molecular conformations significantly influenced the emission wavelengths and efficiencies. Two molecules exhibited longer emissions in the deep red/near-infrared region with higher efficiencies, which is unusual for organic solids. The new molecular design and its potential applications in NIR fluorescence sensing and lasing were comprehensively studied based on experimental measurements and theoretical calculations.

Excited-State Intramolecular Proton Transfer Dyes with Dual-State Emission Properties: Concept, Examples and Applications

Timothee Stoerkler et al.

Summary: Dual-state emissive (DSE) fluorophores are organic dyes that can emit fluorescence in both dilute and concentrated solution and in the solid-state. This review focuses on the utilization of excited-state intramolecular proton transfer (ESIPT) fluorescence to optimize the properties of DSE dyes. The synergistic approach between organic synthesis, fluorescence spectroscopy, and ab initio calculations plays a crucial role in the construction and optimization of DSE-ESIPT fluorophores.
