"Chromophores that absorb in the far-red region of the spectrum are increasingly being utilized for applications in the biosciences. We have synthesized and evaluated a novel series of fluorescent oxonols based on thiobarbituric acids containing aryl and heteroaryl substituents," scientists writing in the journal Analytical Biochemistry report.
"The novel chromophores possess narrow absorption spectra ( approximately 40-nm bandwidths), reasonable Stokes shifts (approximately 25 nm), and quantum yields of up to 0.67 in organic solvents and 0.3 in aqueous solvents, with absorption...
