“…Moreover, in the case of the organic dye impregnated nanofibers, the nanoconfined organic dyes undergo a charge or energy transfer, resulting in the enhancement of the fluorescence signal [10,11]. In addition, fluorescent nanofibers have potential use in chemical and bio-sensing applications [12,13]. The sensing performance is improved by the extended effective surface area of the nanofibers.…”

The decay dynamics of perylene dye molecules encapsulated in polymer nanofibers produced by electrospinning of polymethyl methacrylate are investigated using a confocal fluorescence lifetime imaging microscopy technique. Time-resolved experiments show that the fluorescence lifetime of perylene dye molecules is enhanced when the dye molecules are encapsulated in a threedimensional photonic environment. It is hard to produce a sustainable host with exactly the same dimensions all the time during fabrication to accommodate dye molecules for enhancement of spontaneous emission rate. The electrospinning method allows us to have a control over fiber diameter. It is observed that the wavelength of monomer excitation of perylene dye molecules is too short to cause enhancement within nanofiber photonic environment of 330 nm diameters. However, when these nanofibers are doped with more concentrated perylene, in addition to monomer excitation, an excimer excitation is generated. This causes observation of the Purcell effect in the threedimensional nanocylindrical photonic fiber geometry.

Tables 1-3 contain details of the measurement method and a list of the atoms including atomic coordinates and displacement parameters. Source of materialTo a solution of imidazole (0.681 g, 0.01 mol) in THF (25 mL), 3,6-dibromo-9H-carbazole (1.625 g, 0.005 mol) and NaH (0.24 g, 0.01 mol) was added and the mixture was heated at 60°C. When TLC monitoring indicated no further progress in reaction, the solvent was evaporated and crude mixture was suspended in water (100 mL). The organic

“…The low critical gelation concentrations (CGC) for TPEICE, TPEC and TPECBr in the above solvents were in the range of 2.2e8.2 mM, 0.7e8.3 mM, 3.7e18.4 mM, respectively. TPEC could be considered as a supergelator for acetic acid due to the low CGC of 0.7 mM [5]. The obtained gels were stable for several months at room temperature and could be destroyed when heated.…”
