A calixdiquinone bis-indoaniline derivative with two kinds of potential binding sites, discriminates cations according to their charge/size ratio. Harder and highly oxophilic Eu(III) preferentially interacts with the lower rim quinone oxygens; whereas Na(I) binds to the azacrown moieties. As a consequence of the chromogenic sensor s design, these two binding events result in two different responses, Eu(III) causes a remarkable auxochromic change, but Na(I) produces a significant anti-auxochromic effect.

Enhancing the power conversion efficiency of polymer solar cells via selection of quinoxaline substituents KARAGACTI, Ozge; CEVHER, ŞEVKİ CAN; HIZALAN, Gonul; HACIOGLU, Serife O.; Toppare, Levent Kamil; Çırpan, Ali (2017-12-07) In this study, three random copolymers including quinoxaline derivatives with different substituent groups, 2,6-bis(trimethylstannyl)-4,8-bis(2-ethylhexyloxy) benzo[1,2-b: 4,5-b'] dithiophene and 4,7-dibromo2-(2-octyldodecyl)-2H-benzo[d][1,2,3] triazole, were designed and synthesized according to the donoracceptor (D-A) approach. H-1 NMR spectroscopy, UV-Vis absorption spectroscopy, cyclic voltammetry, and gel permeation chromatography were utilized for the characterization of the polymers. Optical studies ...
Excimer emission and energy transfer in cofacial boradiazaindacene (BODIPY) dimers built on a xanthene scaffold Saki, N; Dinc, T; Akkaya, EU (2006-03-13) Using a rigid xanthene scaffold, a series of boradiazaindacene derivatives were synthesized. In some of these compounds, two boradiazaindacene derivatives were placed cofacially, resulting in significant inter-chromophoric interactions, including excimer emission. A simple modification of boradiazaindacene structure leads to formation of an ICT dye, which has distinct spectral properties. Energy transfer between two BODIPY dyes was demonstrated as well. In addition, the spectral properties of ICT dye can be...
Loss of function of Arabidopsis C-terminal domain phosphatase-like1 activates iron deficiency responses at the transcriptional level Aksoy, Emre; Jeong, In Sil; Koiwa, Hisashi (2013-1-01) The expression of genes that control iron (Fe) uptake and distribution (i.e. Fe utilization-related genes) is tightly regulated. Fe deficiency strongly induces Fe utilization-related gene expression; however, little is known about the mechanisms that regulate this response in plants. Transcriptome analysis of an Arabidopsis (Arabidopsis thaliana) mutant defective in RNA polymerase II C-terminal domain-phosphatase-like1 (CPL1) revealed significant up-regulation of Fe utilization-related genes (e.g. IRONREGUL...
Real-Time PCR Investigation of the Dynamic Expression of Three "RNA Processing and Modification" Genes of Phanerochaete chrysosporium Exposed to Lead Tekın, Elif; İçgen, Bülent; Özcengiz, Gülay (Springer Science and Business Media LLC, 2013-01-01) The expression of three ribosome binding proteins namely; polyadenylate-binding protein, splicing factor RNPS1 and ATP-dependent RNA helicase of Phanerochaete chrysosporium exposed to lead were analyzed by real-time PCR. The mRNA level of splicing factor RNPS1 showed 2.7 (p < 0.05), 2.6 (p < 0.05) and 4.9-fold (p < 0.001) increase when the cells were exposed to 25, 50 and 100 mu M lead, respectively. 50 and 100 mu M lead exposure resulted in almost 2-fold (p < 0.01and p < 0.05, respectively) increase in the...
Positional effect of phenylene moiety on a certain perylene chromophore: A semiempirical treatment Tuerker, Lemi; Atalar, Taner (Informa UK Limited, 2007-01-01) A benzimidazole derivative of perylenetetracarboxylic-3,4,9,10 anhydride has been considered as the base system. Then, by means of annellation ( phenylene fusion) a series of nonexistent structures have been constructed. The positional effect of annellation on these systems has been analyzed theoretically by performing PM3/RHF type quantum chemical calculations. The geometries and stabilities are discussed. The theoretical electronic spectra have been produced by using ZINDO/S ( CI) type calculations and di...
