, p. 3266 - 3269 (2008)
(Figure Presented) Hexano- and dodecano-tethered diesters of rhodamine B were prepared. The absorption and fluorescence spectra of these flexibly tethered dyads were compared with those of the rhodamine 3B ethyl ester. Increased J- and H-type dimer format

PURPOSE: A compound used as a dye is provided to enhance high molar extinction coefficient and spectrometric concentrate. CONSTITUTION: A compound is denoted by chemical formula (0). In chemical formula (0), R2 is hydrogen atom, -CN, or -CONH_2; R3 is alkyl group of 1-4 carbon atoms; and R4a-R7a are independently -R^8, OR^8, -COOR^8, -COR^8, -OCOOR^8, -OCOR^8, -CN, -NO^2, halogen atom, -SO_3H, -SO_3Na,-SO_3K, -SO_2NR, 8R9, or -NR^ll R^12. A dye contains the compound as an active ingredient. A coloring resin composition contains the dye, resin, and solvent.
1H and 13C NMR spectra of commercial rhodamine ester derivatives
Ramos,Vilhena,Santos,Almeida
, p. 475 - 478 (2007/10/03)
Ethyl and methyl esters of commercial rhodamines B, 19, 101 and 110 and propyl and butyl esters of commercial rhodamine B were synthesized and isolated with different counterions (yields 70-98%). The 1H and 13C NMR spectral data for these compounds were fully assigned by a combination of one-and two-dimensional experiments. The Fourier transform IR and UV-visible spectra were also recorded and the main bands were identified. Copyright
