Metal oxide nanostructures are extremely fascinating smart and functional materials owing to their outstanding wide tunable band gap, biocompatibility, high electrochemical coupling coefficient, photostability excellent piezoelectric properties.

The obtained ZJU-28⊃CsPbX 3 crystals exhibit giant two-photon action cross-section and photostability enhancement due to the effects of confinement, passivation separation derived from ZJU-28 frameworks.

An AIPE-active iridium(III) complex was found to possess high specificity for mitochondria, superior photostability, low cytotoxicity, and high resistance to the loss of mitochondrial membrane potential. Thus, this complex can be used for mitochondrial imaging and tracking in living cells.

A tetraphenylethene derivative with a structure resembling Tamoxifen is designed and synthesized as a theranostic agent for cell imaging and anti-breast cancer therapy. Its high brightness, excellent photostability and long-term cell tracing properties enable elucidation of its working mechanism and hence provide new insights into drug development.

High-quality water-soluble near-infrared emitting quantum dots (QDs) are synthesized using a two-step approach for the first time. The CdS shell efficiently increases the structural stability of PbS QDs during water transfer and leads to good photostability and a significantly enhanced quantum yield as high as 30% in buffer.

We report a two-photon fluorescent probe (AHg1) that can be excited by 780 nm femto-second pulses, shows high photostability and negligible toxicity, and can visualize the site of Hg(2+) accumulation, but can also estimate trace amounts of mercury ions in fresh fish organs by two-photon microscopy.

The isolation and characterization of a kinetically stable oxadiazaborinine (ODB) dye are described, which undergoes an unexpected thermal boron rearrangement with color change increase in fluorescence. This controllable reaction allows for the use as practical time-temperature indicator probe advantages photostability, non-reversibility, environmental friendliness.

Herein, we show that a far-red arylidene-squaraine dye is stable against nucleophiles, in contrast to arene-squaraines. Owing to the fluorescence enhancement in apolar media together with high brightness and photostability, this dye was successfully applied to detect the oxytocin G protein-coupled receptor and monitor its internalization in living cells.
