The complexes [Ru(CN)4(HAT)]2-, [{Ru(CN)4}2(mu2-HAT)]4- and [{Ru(CN)4}3(mu3-HAT)]6- (HAT = hexaaza-triphenylene) contain four, eight and twelve externally-directed cyanide ligands, respectively; they show strongly solvatochromic and intense MLCT absorptions, and [3]6- forms a high-dimensionality cyanide-bridged coordination network with Nd(III), in which Ru --> Nd energy transfer results in sen...

The polarity of a series of ionic liquids (ILs) based on hydroxyethyl-imidazolium moiety with various anions ([PF(6)], [NTf(2)], [ClO(4)], [DCA], [NO(3)], [AC], and [Cl]) and their corresponding nonhydroxyl ILs was investigated by solvatochromic dyes and fluorescence probe molecules. Most of the nonhydroxyl ILs exhibit anion-independent polarity with similar E(T)(30) in the narrow range of 50.7...

Labeling of metastatic tumors can aid in their staging and resection of cancer. Near infrared (NIR) dyes have been used in the clinic for tumor labeling. However, there can be a nonspecific uptake of dye by the liver, lungs, and lymph nodes, which hinders detection of metastasis. In order to overcome these problems, we have used two NIR dyes (DyLight 650 and 750) conjugated to a chimeric anti-c...

The use of reactive dyes has increased rapidly due to outstanding properties, growing consumption of cellulosic fibers, and decrease in the production of other application classes of dyes for cellulosics because of cost and health hazards. However, reactive dyes cause the greatest effluent problems for the dye industry. This study explored reusing these dyes in which the residual dyeings were d...

objective: the aim of the present study was to evaluate the efficacy of two caries detector dyes in the diagnosis of dental caries. materials and methods: twenty extracted human posterior teeth without pulpal exposure were sectioned mesiodistally through the center of the lesions using a water-cooled disk. the tooth halves were randomly divided into two groups and treated with caries detector (...
