2,5-Diaminoterephthalates (DATs) are known to be intensely colored and fluorescent compounds that are quite open to functionalization. Even though their conjugated structure is significantly shorter/smaller than that of its popular counterparts such as fluoresceins and BODIPYs, they possess comparable optical properties. Most prominently, DATs have been used as organic linkers for metal organic framework (MOF) materials, and as fluorescent sensors. Despite the existence of chiral DAT derivatives, their chiroptical properties remain obscure. In this study, 6 novel chiral DAT derivatives were designed and synthesized. The designs were first evaluated in silico by DFT calculations. Their optical and chiroptical properties were explored using UV-Vis, fluorescence, and circular dichroism (CD) spectroscopies. In general, their optical properties showed dependence on the hydrogen bonding ability of the solvent, and hence showed promising properties as chiroptical sensors.

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.
Synthesis of azobenzene containing macrocycles
Hoşgör, Ege; Akdağ, Akın; Department of Chemistry (2021-2-10)
Aromatic azo compounds are one of the well-known research topics of recent times due to their photoisomeric properties under ultraviolet or visible light. Generally, these substances undergo isomerization from the thermodynamically more stable trans isomer to the cis isomer when irradiated with appropriate light radiation. The incorporation of azo groups to the macrocycle skeleton is an important part of the supramolecular chemistry. Azobenzene photoisomerization is the key mechanism of molecular motors tha...
Synthesis and ion sensing properties of novel boradiazaindacene dyes
Zalim, Nalan; Akkaya, Engin Umut; Department of Chemistry (2003)
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 th...
Synthesis and modifications of polyprethanes for biomedical purposes
Hasırcı, Nesrin (2007-10-01)
Polyurethanes are known as a class of polymers with very high 'hemocompatible' properties. In this study polyurethanes were prepared in various compositions and in medical purity without using any solvent, catalyst or additives. For the synthesis of polyurethanes, toluene diisocynate, diphenylmethane diisocynate or hexamethylene diisocynate were used as diisocyanate compounds and polypropylene-ethylene glycol or polypropylene glycol were used as polyol compounds. The surfaces were modified with plasma glow-...
Removal of boron from aqueous solutions by continuous polymer-enhanced ultrafiltration with polyvinyl alcohol
Dilek, C; Ozbelge, HO; Bicak, N; Yılmaz, Levent (2002-01-01)
Boron is a highly contaminating metal due to its toxic effects for plants even at very low concentrations. Continuous polymer-enhanced ultrafiltration (PEUF) was applied for removal of boron from aqueous solutions. The effects of operating parameters on the performance of PEUF were investigated. A commercial polymer, polyvinyl alcohol (PVA) was used as the boron-complexing agent. The methodology consists of two steps: complexing boron with PVA following separation of boron and polymer complexes by ultrafilt...
