title = "Syntheses and photophysical properties of aminobenzopyranoxanthene dyes containing various alkyl chains at amine moieties",
abstract = "Aminobenzopyranoxanthene (ABPX) dyes containing linear n-alkyl chains at amino groups were synthesized, and their cis and trans stereoisomers were isolated. Detailed spectrophotometric studies revealed that all the ABPX derivatives exhibited fluorescence emission in the far-red and near-infrared wavelength regions, and their fluorescence quantum efficiency increased with increasing n-alkyl chain length. Almost no differences in photophysical properties were observed between the cis and trans stereoisomers.",
