Aggregation‐Induced Enhanced Emission of a Dimethylacridan Substituted Pyrimidine Derivative
نویسندگان
چکیده
A pyrimidine chromophore bearing an acridan fragment was synthesized and its photophysical properties were studied. In solution, this compound is characterized by important positive emission solvatochromism with a shift of 5800 cm-1 between nonpolar heptane dichloromethane (DCM) associated large Stokes shifts (up to 9100 in DCM). Mono-exponential fluorescence decays are observed whereas more complicated bi- or three-exponential polar solvents due interplay locally excited charge transfer state. Additionally, Aggregation-Induced Enhanced Emission process demonstrated THF/water mixtures. At low temperature (77K), polymethylmethacrylate (PMMA) thin film, the presence accessible triplet state (T1) which not solution. Finally, we show that it possible protonate film leading panchromatic dual

A new and facile synthetic approach to substituted 2-thioxoquinazolin-4-ones by the annulation of a pyrimidine derivative
A new and facile synthesis of 2-thioxoquinazolin-4-ones by introducing a benzenoid system in the pyrimidine moiety by reacting ethoxymethylene derivatives of 1,3-diarylthiobarbituric acids (DTBA) with active methylene compounds, such as malononitrile and ethyl cyanoacetate, in presence of ZnCl₂ has been developed.
متن کاملStimulation of murine interferon by a substituted pyrimidine.
2-Amino-5-bromo-6-methyl-4-pyrimidinol (U-25,166) induced high levels of circulating interferon in mice when administered either parenterally or orally. Peak titers of interferon were found in the serum between 6 and 12 h after inoculation of the drug. Lower but significant levels of interferon were found in rat serum after administration of U-25,166 by either the intraperitoneal or oral route,...
متن کاملAntagonism of some gibberellin actions by a substituted pyrimidine.
From a comparison of the effects of seven growth retardants and abscisic acid (ABA) on various growth systems, it was found that the gibberellin-regulated growth of lettuce hypocotyls was uniquely inhibited by the growth retardant, alpha-cyclopropyl-alpha-(4-methoxyphenyl)-5-pyrimidine methanol (EL-531). Auxin-regulated growth of coleoptile sections was inhibited by Phosfon and only slightly by...

متن کاملAntibacterial activity of DL 473, a C3-substituted rifamycin derivative.
DL 473 is a 3-[(4-cyclopentyl-1-piperazinyl)iminomethyl] rifamycin SV derivative which inhibited staphylococci, streptococci (including Streptococcus faecalis, Listeria species, and Bacteroides species. DL 473 was less active than rifampin against these species. DL 473 did not inhibit Enterobacteriaceae nor most Pseudomonas species. A combination of DL 473 and vancomycin or nafcillin tested aga...
