نویسندگان
چکیده
A rational synthetic approach to substituted naphtho[1,8-gh]quinolines using intramolecular cyclization in the presence of potassium series (naphthalen-1-yl)isoquinolines is described. The photophysical properties obtained compounds were studied; particular, fluorescence emission was detected range 454 - 482 nm with a quantum yield up 54%. We also calculated HOMO-LUMO energies and optimized molecular structures for resulting fluorophores. Based on results titration, Stern-Volmer constants (up 21587 M-1) detection limits nitroanalytes 1.4 ppm) calculated, confirming possibility their use as potential chemosensors visual nitro-containing explosives.

Synthesis and Photophysical Studies
In this study, three new fluorescein derivatives—5-bromo-4′,5′-dinitrofluorescein (BDNF), 5-bromo-4′,5′-diaminofluorescein (BDAF), and 5-bromo-4′,5′-bis(dimethylamino)fluorescein (BBDMAF)—were synthesized and their pH-dependent protolytic equilibria were investigated. In particular, BBDMAF exhibited pH-dependent fluorescence, showing strong emission only at pH 3–6. BBDMAF bears a bromine moiety...
متن کاملSynthesis and electrochemical and photophysical studies of tetrathiafulvalene-annulated phthalocyanines.
The synthesis of tetrakis(tetrathiafulvalene)-annulated metal-free and metallophthalocyanines 5-8 via the tetramerization of the phthalonitrile derivative 4 is reported. All of them have been fully characterized by electronic absorption spectroscopy, thin-layer cyclic voltammetry, mass spectrometry, and elemental analysis. Their solution electrochemical data show two reversible four-electron ox...
متن کاملAlkynyl triphosphine copper complexes: synthesis and photophysical studies.
A rigid triphosphine PPh2C6H4-PPh-C6H4PPh2 () reacted with Cu(+) and a stoichiometric amount of terminal alkyne under basic conditions to give a family of copper(i) alkynyl compounds [Cu()C[triple bond, length as m-dash]CR]. The number of terminal -C[triple bond, length as m-dash]CH groups in the starting ligand determines the nuclearity of the resulting complexes giving mono- (, R = Ph; , R = ...
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 کاملSorptive removal of nitro explosives and metals using biochar.
The feasibility of using biochar as a sorbent to remove nitro explosives and metals from contaminated water was investigated through batch experiments. Biochar, synthesized using various biomasses, showed a porous structure and a high surface area and includes embedded carbonate minerals. Compared with granular activated carbon, biochar was competitive as a sorbent for removing Cd, Cu, Pb, and ...
