Abstract
Optical three-dimensional (3D) molecular imaging is highly desirable for providing precise distribution of the target-of-interest in disease models. However, such 3D imaging is still far from wide applications in biomedical research; 3D brain optical molecular imaging, in particular, has rarely been reported. In this report, we designed chemiluminescence probes with high quantum yields, relatively long emission wavelengths, and high signal-to-noise ratios to fulfill the requirements for 3D brain imaging in vivo. With assistance from density-function theory (DFT) computation, we designed ADLumin-Xs by locking up the rotation of the double bond via fusing the furan ring to the phenyl ring. Our results showed that ADLumin-5 had a high quantum yield of chemiluminescence and could bind to amyloid beta (Aβ). Remarkably, ADLumin-5's radiance intensity in brain areas could reach 4 × 107 photon/s/cm2/sr, which is probably 100-fold higher than most chemiluminescence probes for in vivo imaging. Because of its strong emission, we demonstrated that ADLumin-5 could be used for in vivo 3D brain imaging in transgenic mouse models of Alzheimer's disease.

Abstract
Several peptides and a protein with an inter- or intramolecular cation-π interaction between tryptophan (Trp) and an amine cation are shown to absorb and fluoresce in the visible region of the spectrum. Titration of indole with sodium hydroxide or ammonium hydroxide yields an increasing visible fluorescence as well. Visible absorption and multipeaked fluorescence excitation spectra correlate with experimental absorption spectra and the vibrational modes of calculated absorption spectra for the neutral Trp radical. The radical character of the cation-indole interaction is predicted to stem from the electrostatic dislocation of indole highest occupied molecular orbital (HOMO) charge density toward the cation with a subsequent electronic transition from the HOMO-2 to the HOMO. Because this is a vertical transition, fluorescence is possible. Hydrogen bonding at the indole amine most likely stabilizes the radical-like state. These results provide new spectroscopic tools for the investigation of cation-π interactions in numerous biological systems, among them, proteins and their myriad ligands, and show that one, or at most, two, point mutations with natural amino acids are all that is required to impart visible fluorescence to proteins.
