TL;DR: Results indicate that, while the optical band gap depends on the actual electron-hole recombination within the nanocrystal, and therefore follows the size dependence expected from the particle-in-a-box model, the electrochemical processes of these QDs are strongly affected by other factors, such as the presence of surface defects.

TL;DR: Three compounds incorporating a BODIPY fluorophore and an oxazine photochrome within the same molecular skeleton and differing in the nature of the linker bridging the two functional components can ultimately lead to the development of valuable photoswitchable fluorescent probes for the super-resolution imaging of biological samples.

TL;DR: In this article, an oxazine auxochrome and a carbazole chromophore are integrated within the same covalent skeleton to generate a halochromic molecular switch.

TL;DR: Photoisomerization of a coordinating, photochromic dithienylethene bearing a pyridine and a methylpyridinium group was investigated as a means to reversibly modulate the luminescence from CdSe-ZnS core-shell quantum dots, suggesting irreversible electron transfer from the quantum dot to the dithielthene as the dominant luminescent quenching mechanism.

TL;DR: The transduction mechanisms can successfully be exploited to signal the presence of target analytes with luminescence changes, and can ultimately lead to the development of innovative luminescent chemosensors based on the unique photophysical properties of semiconductor quantum dots.
