Polarity, as a complex parameter, plays pivotal roles in chemistry and biology. Deviant
polarity change in different subcellular compartments is closely connected with diseases …

Dicyanoisophorone (DCI) has been used extensively as a quality acceptor for designing
chemical sensors targeting different analytes, and developing a series of well-established …

Far-red and near-infrared (NIR) fluorescent materials possessing the characteristics of
strong two-photon absorption and aggregation-induced emission (AIE) as well as specific …

The traditional design strategies for highly bright solid‐state luminescent materials rely on
weakening the intermolecular π–π interactions, which may limit diversity when developing …

In this perspective, we present an overview of the determination of excited-state properties of
“real-life” dyes, and notably of their optical absorption and emission spectra, performed …

Mitochondrial polarity strongly influences the intracellular transportation of proteins and
interactions between biomacromolecules. The first fluorescent probe capable of the …

Compared with traditional one‐photon fluorescence imaging, two‐photon fluorescence
imaging techniques have shown advantages such as increased penetration depth, lower …

Based on OR logic gate, we proposed a smart near-infrared (NIR) fluorescent probe, named
VPCPP, for simultaneously monitoring local microviscosity, micropolarity, and …

Three-photon fluorescence microscopic (3PFM) bioimaging is a promising imaging
technique for visualizing the brain in its native environment thanks to its advantages of high …

Design of chemical probes with high specificity and responses are particularly intriguing. In
this work, a fluorescent probe (M–OH–SO 3) with dual-channel spectral responses toward …
