Molybdenum(VI) oxodiperoxo complex containing an oxazine ligand, ([MoO(O-2)(2)(phox)], phox: 2-(2'-hydroxyphenyl)-5,6-dihydro-1,3-oxazine) was conveniently synthesized and immobilized onto chloro-functionalized mesoporous silica SBA-15 by covalent bonding between the chloropropyl group on the internal surface of the pores and the nitrogen atom of oxazine ligand yielding [MoO(O-2)(2)(phox)]/SBA-15. The resulting material was characterized by FT-IR, TGA, XRD, SEM, TEM, EDX, ICP-AES, BET and UV-vis spectroscop...

Özdemir Hacıoğlu, Şerife; Aktaş, Ece; Hızalan Özsoy, Gönül; Ünlü, Naime; Çırpan, Ali; Toppare, Levent Kamil (null; 2016-06-20)
Conjugated polymers (CPs) have attracted considerable interest due to their tunable electronic and optical properties via combination of different subgroups. These certain advantages increase the popularity of these materials and in recent years they have been widely used as active materials in different fields such as; electrochromic devices (ECDs) [1], light emitting diodes (OLEDs) [2] and photovoltaic devices (OPVs) [3]. For these variety of applications, combining donor and acceptor groups in the polym...
Azaindole-BODIPYs: Synthesis, fluorescent recognition of hydrogen sulfate anion and biological evaluation
Kesan, Gurkan; Topaloglu, Burcu; Ozcan, Emrah; Kazan, Hasan Huseyin; TANRIVERDİ EÇİK, ESRA; ŞENKUYTU, ELİF; ŞENGÜL, İBRAHİM FAZIL; KANDEMİR, HAKAN; ÇOŞUT, BÜNYEMİN (2019-04-15)
The synthesized and sensing capability of two novel azaindole substituted mono and distyryl BODIPY dyes against bisulfate anion were reported. Structural characterizations of the targeted compounds were conducted by using matrix-assisted laser desorption/ionization time-of-flight mass spectrometry, H-1 and C-13 NMRspectroscopies. Photophysical properties of the azaindole substituted BODIPY compounds were investigated employing absorption and fluorescence spectroscopies in acetonitrile solution. It was found...
Benzodithiophene and Benzotriazole Bearing Conjugated Polymers for Electrochromic and Organic Solar Cell Applications
UNLU, Naime Akbasoglu; HACIOGLU, Serife O.; HIZALAN, Gonul; Yildiz, Dilber Esra; Toppare, Levent Kamil; Çırpan, Ali (The Electrochemical Society, 2017-01-01)
Herein, alternating donor-acceptor type benzodithiophene and benzotriazole bearing copolymers were synthesized and thieno[3,2-b] thiophene and furan units were incorporated as pi-bridges. The application of these polymers for electrochromic and photovoltaic studies were performed. Spectroelectrochemical studies illustrate that both polymers showed multichromic behavior due to tailoring of polaron bands in visible region. Photovoltaic properties of P2 were performed by conventional device structure. The best...
Organosilanols as Catalysts in Asymmetric Aryl Transfer Reactions
Özçubukçu, Salih; BOLM, Carsten (American Chemical Society (ACS), 2005-03-01)
Various ferrocene-based organosilanols have been synthesized in four steps starting from achiral ferrocene carboxylic acid. Applying these novel planar-chiral ferrocenes as catalysts in asymmetric phenyl transfer reactions to substituted benzaldehydes afforded products with high enantiomeric excesses. The best result (91% ee) was achieved in the addition to p-chlorobenzaldehyde with organosilanol 2b, which has a tert-butyl substituent on the oxazoline ring and an isopropyl group on the silanol fragment.
