Selective nucleophilic substitution on a perfluorophenyl unit comprising a BODIPY fluorophore using an alkanethiol or a primary amine offers a quantitative fluorophore labelling strategy, while retaining high photostability and emission quantum yields approaching unity.
A novel class of ZnSalens (ZnL(1-10)) with lipophilic and cationic conjugates as optical probes in single and two-photon fluorescence microscopy images of living cells were prepared, which exhibited chemo- and photostability, low cytotoxicity and high subcellular selectivity.
A high quantum yield and an enhanced photostability was found for a europium(III) tetrakis(2-thenoyltrifluoroacetonate) complex after dissolving the complex in a weakly-coordinating imidazolium ionic liquid.
The photodimerization reaction between the two adjacent thymine bases within a single strand has been the subject of numerous studies due to its potential to induce DNA mutagenesis and possible tumorigenesis in human skin cells. It is well established that the cycloaddition photoreaction takes place on a picosecond time scale along barrierless or low barrier singlet/triplet pathways. However, t...
The main aim of this study was determination of thermo- radio- and photostability ofperindopril tert-butyloamine (PER) therefore the efficiency and safety of the therapy could bemaintained.A chromatographic method (RP-HPLC) had been validated before use to determinePER loss. The evaluation of stability properties of PER in solid state under the influence ofisothermal condition, relative humidit...
Water-soluble tetraazaperopyrene (TAPP) derivatives have been synthesized, which show both high photostability and high fluorescence quantum yields (>80%) in water. Furthermore delivery of the dye into cells demonstrated selective staining of the nucleus.
We have fabricated organic polariton microcavities that exhibit remarkable photostability, even in the condensation regime.
