The derivatives of boradiazaindacene (BODIPY) are highly fluorescent dyes which have quantum yields near 1.0. These dyes that have exceptional spectral and photophysical stability as compared to other fluorescent groups are used for several different applications. The fluorescent sensor molecules for the detection of cations with PET (photoinduced-electron transfer) mechanism in general have been obtained by the differentiation of the BODIPY core. The extension of conjugation over the pyrrole ring shifts the absorption and emission at longer wavelength. Moreover, it is seen that red emission occurs from an ICT (intramolecular-charge transfer) state.In this study, we designed and synthesized an unsymetrically substituted BODIPY dye series, carrying a cation-sensitive phenylazacrown ether group conjugated to the core, and investigated the ion sensing properties of these compounds. Both aza-crown derivatives displayed selectivity towards Ca(II)

Synthesis of some novel derivatives of 2,6-diaminoanthraquinone dyes
Yildirir, Yilmaz; Özdemir, Melek; Disli, Ali; Çolak, Naki (2008-11-01)
In present study, some derivatives of 2,6-diaminoanthraquinone dyes are synthesized and their UV-visible spectra are investigated in various conditions. Ten compounds (la-e) and (2a-e), two of which (1a, 1b) were previously obtained in low yields, have been synthesized by using diazonium salts of 2,6-diaminoanthraquinone and characterized by spectroscopic methods.
Preparation and photocatalytic activity of g-C3N4/TiO2 heterojunctions under solar light illumination
Gundogmus, Pelin; PARK, JONGEE; Öztürk, Abdullah (Elsevier BV, 2020-09-01)
The solar light sensitive g-C3N4/TiO2 heterojunction photocatalysts containing 20, 50, 80, and 90 wt% graphitic carbon nitride (g-C3N4) were prepared by growing Titania (TiO2) nanoparticles on the surfaces of g-C3N4 particles via one step hydrothermal process. The hydrothermal reactions were allowed to take place at 110 degrees C at autogenous pressure for 1 h. Raman spectroscopy analyses confirmed that an interface developed between the surfaces of TiO2 and g-C3N4 nanoparticles. The photocatalyst containin...
Growth and characterization of PbMo0.75W0.25O4 single crystal: A promising material for optical applications
Isik, M.; Hasanlı, Nızamı; Darvishov, N.H.; Bagiev, V.E. (2023-02-15)
The present paper reports the structural and optical properties of PbMo0.75W0.25O4 single crystals grown by Czochralski method. XRD pattern of the crystal indicated well-defined two diffraction peaks associated with tetragonal crystalline structure. Raman and infrared spectra of the grown single crystals were presented to get information about the vibrational characteristics. Observed Raman modes were associated with modes of PbMoO4 and PbWO4. Eight bands were revealed in the infrared spectrum. The bands ob...
Synthesis, characterization, and theoretical investigation of optical and nonlinear optical (NLO) properties of triazene-based push–pull chromophores
Mammadova, Flora; Ozsinan, Semin; Okutan, Merve; Dengiz, Çağatay (Elsevier BV, 2020-11-15)
A short and efficient synthetic strategy for the synthesis of triazene-substituted push–pull dyes has been developed. The formal [2 + 2] cycloaddition-retroelectrocyclization was utilized for the preparation of the target push–pull dyes. These atom-economic, click-type chemical transformations occurred under ambient conditions and provided structurally interesting push–pull dyes in high yields. The effects of different triazene substituents on optical and non-linear optical properties were investigated by m...
Production of boron nitride by carbothermic and mechanochemical methods, and nanotube formation
Camurlu, HE; Aydogdu, A; Topkaya, Yavuz Ali; Sevinc, N (2003-09-12)
The formation of hexagonal boron nitride by carbothermic reduction of boron oxide and nitridation has been examined. Experiments were conducted in the temperature range of 1100-1500degreesC for durations between 15-240 minutes. Products were examined by X-ray, SEM and chemical analysis. The results showed that the reaction proceeds through a gaseous boron containing species, which is most probably 13203(g). It was found that all of the carbon was consumed and formation of boron nitride was complete in 2 hou...
