Photophysical properties of 5-substituted 2-thiopyrimidines.
The aim of the present work is to determine the influence of C5 substitution on the photophysical properties of 2-thiopyrimidines (2-TPyr). For this purpose, 2-thiouracil, 5-t-butyl-2-thiouracil and 2-thiothymine (TU, BTU and TT, respectively) have been selected as target thionucleobases for the experimental studies and, in parallel, for DFT theoretical calculations. The UV spectra displayed by...
متن کاملSynthesis of 2-chloro 5-nitro 9,10-anthraquinone and the study of photophysical properties
Literature survey revealed that a good number of anthracene and substituted anthracences are potential lasing organic compounds. As per Mitsuo Maeda 9,10 dimethyl and 9,10 diphenyl anthracenes exhibit lasing properties around, 435-450nm. In continuation of our studies27 it was proposed to synthesize new lasing organic dyes in particular, new anthracene derivatives and study their photophysical ...
متن کاملSyntheses and photophysical properties of 5'-6-locked fluorescent nucleosides.
Nine fluorescent 5'-6-locked nucleosides were synthesized by condensation of various 1,2-diketones with 5-amino-2'-deoxycytidine. The nucleosides have different substituents on the pyrazine core structure, ranging from two methyl groups to polyaromatic rings. The photophysical properties of each nucleoside were determined, with the nucleosides displaying diverse absorption and emission maxima, ...
متن کاملPhotophysical properties of 3-[2-(N-phenylcarbazolyl)benzoxazol-5-yl]alanine derivatives--experimental and theoretical studies.
Solvatochromic probes are often used in biophysical studies to obtain information about polarity of the microenvironment. As there is not much natural fluorophores with such properties, there is still need for new synthetic compounds such as 3-(2-benzoxazol-5-yl)alanine derivatives. Among this group of non-proteinogenic fluorescent amino acids especially interesting are 3-[2-(4-aminophenyl)benz...
متن کاملSynthesis and Photophysical Properties of Polycarbo-Substituted Quinazolines Derived from the 2-Aryl-4-chloro-6-iodoquinazolines.
The reactivity of the 2-aryl-4-chloro-6-iodoquinazolines towards palladium catalyzed sequential (Sonogashira/Suzuki-Miyaura) and one-pot two-step cross-coupling (bis-Sonogashira, and successive Sonogashira/Stille) reactions to afford novel unsymmetrical polycarbo-substituted quinazolines has been evaluated. In contrast to the chloro-bromo substituted quinazolines in which selectivity has been p...
