The synthesis and characterization of meso-piperidine linked Bodipy starting from 4-(2-(piperidine-1-yl)ethoxy) benzaldehyde was described. Meso-piperidine linked Bodipy was subsequently used for the construction of distyryl-piperidine-Bodipy and distyryl-morpholine-Bodipy via Knoevenagel type reaction. The photophysical properties including molar extinction coefficient, fluorescence lifetime and fluorescence quantum yield of Bodipys were investigated in ethanol solution. The targeted compounds were also assessed in live cell imaging and cytotoxicity studies by using breast cancer cell line, MCF-7 in vitro.


Absorption spectrum of monomeric pseudoisocyanine: A new perspective and its implications for formation and spectral response of J-aggregates in solution and in thin films
Gulen, Demet; ÖZÇELİK, Serdar (Elsevier BV, 2008-05-01)
We argued against the current spectral assignment for absorption spectrum of monomeric PIC which is widely accepted since the pioneering works of Scheibe and Jelley [G. Scheibe, Angew. Chem. 49 (1936) 563; E.E. Jelly, Nature 138 (1936) 1009]. A new spectrum is presented along with its conceptual basis. The hypothesized spectrum attributes the previous 0-0 (approximate to 525 nm) and 0-1 (approximate to 490 nm) assignments, respectively, to intermediates acting as the precursor of J-aggregates and to the 0-0...
TL and TSC studies on TlGaSe2 layered single crystals
Isik, M.; Bulur, Enver; Hasanlı, Nızamı (Elsevier BV, 2013-12-01)
Defects in - as grown - TlGaSe2 layered single crystals were investigated using Thermoluminescence (TL) and Thermally Stimulated Currents (TSC) techniques in the temperature range 10-300 K. TL and TSC curves of samples illuminated using a light with energy greater than the band gap of the material, i.e. blue light (similar to 470 nm) at 10 K, exhibited peaks around 27 and 28 K, respectively, when measured by heating up the samples at a rate of 1 K/s. TL and TSC curves were analyzed to characterize the defec...
TL and OSL studies on gallium sulfide (GaS) single crystals
Isik, M.; YÜKSEL, MEHMET; TOPAKSU, MUSTAFA; Hasanlı, Nızamı (Elsevier BV, 2020-09-01)
Gallium sulfide (GaS) single crystals were investigated using thermoluminescence (TL) and optically stimulated luminescence (OSL) measurements. TL experiments performed in the room temperature (RT)-450 °C range presented a glow curve consisting in six single discrete peaks. Analyses of TL glow curve by computerized glow curve deconvolution method showed that the trapping centers responsible for peaks are located at 0.98, 1.09, 1.15, 1.76, 1.87 and 1.90 eV. The order of kinetics found between 1 and 2 indicat...
Thermal activation energy of crystal and amorphous nano-silicon in SiO2 matrix
Wang, Jiwei; Righini, Marcofabio; Gnoli, Andrea; Foss, Steinar; Finstad, Terje; Serincan, Ugur; Turan, Raşit (Elsevier BV, 2008-09-01)
Temperature and size dependence of photoluminescence (PL) of nano-silicon embedded in SiO2 matrix samples were studied. In these measurements, four samples with deferent implantation dose showed their similar tendency. Their nano-structure was investigated by high resolution electron microscopy (HREM) and selected area diffraction (SAD) which confirmed that only those prepared with the higher Si implantation dose formed crystal nano-silicon. The further analysis of the dependence of thermal activation energ...
Multiphoton core ionization dynamics of polyatomic molecules
Toffolı, Danıele; Decleva, Piero (IOP Publishing, 2013-07-28)
The two-photon core ionization dynamics of gas-phase methane, carbon monoxide and nitrogen have been studied with a recent implementation of the lowest order perturbation theory in the framework of density functional theory and a multicentric basis set expansion of bound and scattering states. Ionization cross sections and angular asymmetry parameters have been calculated for the case of a single radiation beam and for both linear and circular light polarizations in the fixed nuclei approximation. Expected ...
