A simple one-pot hydrothermal approach has been demonstrated for the preparation of highly water soluble and photoluminescent carbon nanodots (C-dots) from low-cost organic compounds. We found that the compounds incorporating amino and carboxylic acid groups are suitable for the preparation of highly photoluminescent and water-soluble C-dots.

Carbon quantum dots (CQDs) are photostable, highly photoluminescent nanomaterials (size≤10 nm; high Φs) throughout the blue-to-red spectral region; their photophysical properties can be tuned by manipulating sizes and shapes, doping surface passivation. The unequivocal biocompatibility low-toxicity of CQDs have made them useful in bioimaging, drug delivery, chemical sensing. They synthesized fr...

Metal–organic frameworks (MOFs) have gained a large amount of interest because their periodic and modular structure. These features allow easy prediction the physical chemical properties an organic chromophore, acting as linker in MOF. In present work, bianthryl (BA) equipped with metal-coordinating carboxylate groups, is studied to construct photoluminescent Zn-BA surface-anchored MOF (SURMOF)...

The formation of nonluminescent aggregates of aluminium sulfonated phthalocyanine in complexes with CdSe/ZnS quantum dots causes a decrease of the intracomplex energy transfer efficiency with increasing phthalocyanine concentration. This was confirmed by steady-state absorption and photoluminescent spectroscopy. A corresponding physical model was developed that describes well the experimental d...

Excited-state intramolecular proton transfer (ESIPT) is a photophysical process that may lead to superior emission properties. For long time, cinnamoyl pyrone (CP) derivatives have been classified as non-ESIPT molecules. With the exception of those bearing strong electron-donor substituent, they considered no interest from spectroscopic point view, because are virtually not fluorescent in solut...

Ozone (O3) gas is widely used as a strong oxidizing agent for many purposes, such as the decomposition/removal of organic contaminants and photoresist, and the deodorization/disinfection of air and water. However, ozone is highly toxic to the human body when the air concentration exceeds about 1 ppm. Therefore, there is increasing demand for simple, sensitive, reliable, and cost-effective techn...
