Syntheses and photophysical properties of aminobenzopyranoxanthene dyes containing various alkyl chains at amine moieties

Kamino, Shinichiro,Tanioka, Masaru,Sawada, Daisuke,Enomoto, Shuichi

, p. 1167 - 1176 (2019/12/11)

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.

Paragraph 0668, (2018/01/04)

A quencher is disclosed having a compound represented by the following general formula (1): wherein R5 each independently represent a halogen atom, an alkyl group, an alkoxy group, an alkylthio group, an amino group having a substituent or not having a substituent, a hydroxy group, an aryl group, an aryloxy group, or an arylalkyl group; R6 represents a group having a polymerizable unsaturated group, a hydroxy group, or the like; Y1 represents an oxygen atom, or the like; An? represents an anion; Ar1 represents a specific ring structure; * and ** represent binding positions; Ar2 represents a benzene ring, a naphthalene ring, or an anthracene ring; n1 represents a specific integer; and the following structure (1-10) in the general formula (1) is an asymmetric structure; (wherein R5, Y1, Ar1, Ar2, n1, * and ** are the same as described above.).

A new class of rhodamine luminophores: Design, syntheses and aggregation-induced emission enhancement

Kamino, Shinichiro,Horio, Yuka,Komeda, Seiji,Minoura, Katsuhiko,Ichikawa, Hayato,Horigome, Jun,Tatsumi, Asana,Kaji, Shinya,Yamaguchi, Takako,Usami, Yoshihide,Hirota, Shun,Enomoto, Shuichi,Fujita, Yoshikazu

supporting information; experimental part, p. 9013 - 9015 (2011/02/16)

A new class of rhodamine luminophores, 3′,3″- bis(oxospiroisobenzofuran)-3,7-bis(dialkylamino)benzopyrano-xanthene derivatives (ABPX), have been successfully developed. The emission behavior of ABPX series is directly opposite to the concentration quenching of conventional rhodamine dyes. ABPX series exhibit aggregation-induced emission enhancement (AIEE).
