Two novel distyryl-boradiazaindacene dyes with dimethylaminostyryl and pyridylethenyl substituents display opposite spectral shifts on protonation with TFA in organic solvents. This bidirectional switching of the dyes can be shown to be directly related to ICT donor and acceptor characteristics of the substituents attached to the BODIPY core. The observed spectral response of these dyes could be very useful in the design of novel NIR fluorescent ratiometric probes for pH.

Distyryl boradiazaindacemes as red and nir switches İşbaşar, Güllü Ceyda; Akkaya, Engin Umut; Department of Chemistry (2007) Two novel distyryl-boradiazaindacene dyes with dimethylaminophenyl and pyridyl appendages, display opposite spectral shifts on protonation with trifluoroacetic acid in organic solvents. This bidirectional switching of the dyes can be shown to be directly related to ICT donor and acceptor characteristics of the dyes. Thus, it has been demonstrated that the switching behavior of the red to NIR emitting dyes can be altered by simple structural modifications.
Immobilization of Invertase in a Novel Proton Conducting Poly(vinylphosphonic acid) - poly(1-vinylimidazole) Network Isikli, Suheda; Tuncagil, Sevinc; Bozkurt, Ayhan; Toppare, Levent Kamil (Informa UK Limited, 2010-01-01) A novel proton conducting polymer blend was prepared by mixing poly(vinylphosphonic acid) (PVPA) with poly(1-vinylimidazole) (PVI) at various stoichiometric ratios via changing molar ratio of monomer repeating unit to achieve the highest protonation. The polymer network having the most suitable stoichiometric ratio for substantial proton conductivity was prepared and characterized by FT-IR spectroscopy and proton conductivity measurements. The network was used for immobilization of invertase and some import...
Hydride generation and preconcentration of bismuth on a single-drop followed by determination using electrothermal atomic absorption spectrometry Dügencili, Başak; Ataman, Osman Yavuz; Department of Chemistry (2015) A novel method for determination of bismuth is proposed where the analyte is converted to its hydride form, BiH3, followed by head space preconcentration on a single aqueous drop; final detection was done using electrothermal atomic absorption spectrometry (ETAAS). The preconcentration step was named as headspace single-drop microextraction (HS-SDME). Experimental parameters for hydride generation using both continuous flow and batch technique, ETAAS and finally HS-SDME were optimized. For HS-SDME, Pd, Ni, ...
Dielectric and Thermal Effects on the Optical Properties of Natural Dyes: A Case Study on Solvated Cyanin Malcıoğlu, Osman Barış; Gebauer, Ralph; Varsano, Daniele; Baroni, Stefano (2011-10-05) The optical properties of the flavylium state of the cyanin dye are simulated numerically by combining Car-Parrinello molecular dynamics and linear-response time-dependent density functional theory calculations. The spectrum of the dye calculated in the gas phase is characterized by two peaks in the yellow and in the blue (green and violet), using a GGA-PBE (hybrid-B3LYP) DFT functional, which would bring about a greenish (bright orange) color incompatible with the dark purple hue observed in nature. Descri...
TRANSPARENT GRAPHENE ANODES FOR ORGANIC LIGHT EMITTING DIODES Sharif, Parisa; Oral, Ahmet; Çırpan, Ali; Department of Micro and Nanotechnology (2021-7-14) This thesis presents a novel method for fabrication of OLEDs on a specific flexible PET substrate with graphene anodes, demonstrating low sheet resistance, high work function, and an extremely high luminance. Firstly, a single-layer graphene growth process with chemical vapor deposition (CVD) method is optimized. Flexible anodes are then fabricated by stacking 7-layers of graphene films and doped with nitric acid to reduce the sheet resistance. Modified few layer graphene anodes by 29 Ω/□ sheet resistance a...
