For a long time, luminescence phenomena were strictly distinguished between the emission
of isolated molecules in dilute solutions or close‐packed structures such as in powders or …

Conspectus Single-benzene fluorophores (SBFs) are small molecules that produce visible
light by using only one benzene ring as the sole aromatic core. This Account centers around …

It is commonly accepted that a large π-conjugated system is necessary to realize low-energy
electronic transitions. Contrary to this prevailing notion, we present a new class of light …

Solution and solid dual photoluminescence (PL) molecules fill the substantial gap between
ACQ and AIE molecules to explore the mechanism of molecular luminescence in greater …

Molecular emitters simultaneously generating light at different wavelengths have wide
applications. With a small molecule, however, it is challenging to realize two independent …

Abstract Design and synthesis of organic luminogens with efficient emission in both solution
and solid-state (namely, dual-state emission: DSE) still face enormous challenges, a …

Organic crystals are easily cracked into pieces or powders under applied stress because of
their intrinsic brittle nature. This undesired mechanical property directly limits their …

Simple donor–acceptor (D–A) molecules with large Stokes-shifted and bright near-infrared
(NIR) emissions are extremely attractive for the high-resolution three-photon fluorescence …

Red‐emissive fluorophores generally consist of large π‐extended systems and thus
encounter the problem of serious fluorescence quenching in the solid state. A series of …

Abundant high-performance organic crystals have been reported in the past decades;
however, applications of crystalline materials are seriously restricted by their notorious …
