A series of novel non-symmetrical coumarin-fused BODIPY dyes were synthesised. Their absorption and emission properties are strongly influenced by substitution in the coumarin moiety. Diethylamino-substituted showed near-IR with large Stokes shifts (up to 144 nm) good fluorescence quantum yields.
Polymeric aromatic amines were shown to be very promising cathodes for lithium-ion batteries. Surprisingly, these materials are scarcely used designing post-lithium In this Letter, we investigate the application of high-voltage poly(N-phenyl-5,10-dihydrophenazine) (p-DPPZ) K-ion The designed batteries demonstrate an impressive specific capacity 162 mAh g-1 at current density 200 mA g-1, operate efficiently high densities 2-10 A enabling charge and discharge within ∼1-4 min, deliver 125-145...

Novel photochromic 5-(3'-coumarinyl)-4-(3''-thienyl)thiazoles have been synthesized. These compounds display intensive fluorescence emission in the open form A, which is modulated by light. Fluorescence intensity decreases significantly upon irradiation of A with UV-light (lambda<400 nm) due to formation cyclic B. Irradiation B visible light (lambda>470 promotes its opening and recovering fluorescence. dihetarylethenes undergo modulation both solution polymeric matrices.
Organic dyes are very promising substrates for modern sensing technologies. Their utility is based on the ‘push-pull’ polarization of a π-electron system, as well their polyfunctionality. These properties make organic capable fluorescent sensory response to many analytes and provide different mechanisms both fluorescence increase quenching. Specific reactions structural transformations under consideration in this review. The data confirming structures products related analytical discussed...

A new BODIPY-coumarin dye was synthesized, characterized, and utilized as a light-sensitive component in optically programmed OFET-based memory cells photodetectors.
Three coumarin-based boron complexes (L1, L2 and L3) were designed successfully incorporated into polymeric matrixes for evaluation as temperature probes. The photophysical properties of the carried out in different solvents solid state. In solution, compound L1 exhibited highest fluorescence quantum yield, 33%, with a positive solvatochromism also being observed on absorption emission when polarity solvent increased. Additionally presence anions, showed colour change from yellow to pink,...
4-Hydroxycoumarin 1, 4,5-dihydroxycoumarin 2, and 4,7-dihydroxycoumarin 3 undergo H–D exchange at the C(3) atom of lactone ring. Although only 4-hydroxy-2-chromenone tautomeric forms are seen in 1 H 13 C NMR spectra compounds 1–3, equilibrium between 2,4-chromandione is suggested to be key step reaction. 4,5-Dihydroxycoumarin shows highest rate reaction, since H-bonding 5-hydroxyl 4-keto functional groups can provide relative stability 5-hydroxy-2,4-chromandione form, a probable intermediate...

Close agreement between experimental the PPP CI calculated electron band energies has found in most cases. Strong polarization carbonyl function pyrone ring 7-hydroxycoumarin derivatives, H-bonding hydroxyl group neighboring substituent ortho-substituted hydroxycoumarins, as well tautomeric transformations, suggested discussion electronic derivatives.

Abstract Novel push-pull fluorescent dyes, 7-(diethylamino)furo[3,2- c ]coumarin and 7-(diethylamino)thieno[3,2- derivatives, were designed synthesized using formyl derivatives of furo- thieno[3,2- ]coumarins as key intermediates. Electron absorption emission spectra the dyes recorded in different solvents. The longest-wave bands electron are suggested to be nature.
