Abstract

We demonstrate that the emission energy of the cypridinid oxyluciferin depends strongly on the polarity and, to a lesser extent, on the basicity of the medium. The emission color can be tuned by environment effects from violet to green. We also provide firm evidence that the natural system utilizes the neutral form of the emitter.

  31. The CAM-B3LYP functional M. J. G. Peach, T. Helgaker, P. Salek, T. W. Keal, O. B. Lutnaes, D. J. Tozer and N. C. Handy, Phys. Chem. Chem. Phys., 2006, 8, 558–562), which is advantageous for treatment of charge-transfer systems, was employed for optimization and vibrational analysis of in vacuo models in the S0 state. The relevant portion of the conformational space was screened by optimizing a set of 16 structures—four conformers, obtained by rotation around the exo-C9-N-C fragment of three tautomers of OLnH and of three forms of OLn– were optimized (for definition of the prefixes, see the ESI). The excited-state (S1) geometries were optimized and the vertical excitation energies (Tv), fluorescence emission energies (Te) and oscillator strengths (f) were calculated with the time-dependent (TD) CAM-B3LYP method, using the basis set 6-31+G(d,p) for all atoms. The calculations were performed by Gaussian 09 program suite: M. J. Frisch, et al., Gaussian, Inc., Wallingford, CT, 2009 (the complete reference is provided in the ESI).

  33. The following scale of emission colors was adopted in this work: violet, 380-450 nm; blue, 450-475 nm; cyan, 475-495 nm; green, 495-570 nm.

  34. We note that these assignments differ from ref. 13 where the emission of the amidate ion in model CL molecules were assigned to bands at 389-401 nm in diglyme/acetate buffer (pH 5.6) and at 467-474 nm in DMSO/base, and the emission of the neutral amide of the same molecules was assigned to bands at 394-491 nm in diglyme/acetate buffer.

  35. This observation confirms that the green emission at 502 nm is not due to irreversible decay (hydrolysis) of the emitter (ref. 3).

  36. A recent theoretical study on 2-acetamido-3-methylpyrazine unraveled differences between the chemiluminescent and fluorescent structures (D. Roca-Sanjuán, M. Delcey, I. Navizet, N. Ferré, Y.-J. Liu and R. Lindh, J. Chem. Theory Comput., 2011, 7, 4060–4069). However, no chemiluminescent structures could be located by the TD DFT method that we employed in this study; nevertheless, such differences might become detectable by performing high-level calculations in the future.
