A matrix isolation study of the fluorescence of anthracene and anthracene-ammonia adducts in solid argon
The UV absorption and emission spectra of anthracene in an argon matrix were measured. Three major spectroscopic systems were observed, assignable to anthracene molecules occupying distinct sites. The origins of these systems were red-shifted with respect to the isolated molecule by 535,69 1 and 722 cm-‘. At 17 K all lines were well resolved, with about 8 cm-’ fwhm. Addition of a small amount o...
متن کاملDansyl-anthracene dyads for ratiometric fluorescence recognition of Cu2+.
Dansyl-anthracene dyads 1 and 2 in CH(3)CN-H(2)O (7:3) selectively recognize Cu(2+) ions amongst alkali, alkaline earth and other heavy metal ions using both absorbance and fluorescence spectroscopy. In absorbance, the addition of Cu(2+) to the solution of dyads 1 or 2 results in appearance of broad absorption band from 200 nm to 725 nm for dyad 1 and from 200 nm to 520 nm for dyad 2. This is a...
متن کاملFluorescence quenching of anthracene by aniline in different solvents
Received 2 September 2003; revised 9 February 2004; accepted 7 May 2004 Fluorescence quenching of anthracene by aniline in five different solvents has been carried out at room temperature with a view to understand the quenching mechanisms. Experimental results show positive deviation in the Stern-Volmer plots in all the solvents studied. In order to interpret these results the ground state comp...
متن کاملSolid-state Intercalation of Naphthalene and Anthracene into Alkylammonium-montmorillonites
Intercalation of naphthalene and anthracene into alkyltrimethylammonium (C, H2. + ~ (CH3)3N+; n = 8, 12, 14, 16, and 18)-montmorillonites was carried out by novel solid-solid reactions at room temperature. Octyltrimethylammoniurn(C8)-montmorillonite did not form an intercalation compound with either naphthalene or anthracene. Naphthalene was intercalated into both dodecyltrimethylammonium(C12)a...
متن کاملA cyclodextrin-insulated anthracene rotaxane with enhanced fluorescence and photostability.
A beta-cyclodextrin anthracene rotaxane was synthesized and found to be significantly more resistant to fluorescence quenching and photobleaching than the uninsulated anthracene derivative.
