In one aspect, the disclosure relates to xanthene-, thiazine-, and oxazine-based dyes containing a phosphinate ester group and having near-infrared (NIR) absorption and methods of making the same. The fluorescence lifetimes and stabilities of the dyes can be tuned by modifying the molecule cores, making them suitable for a variety of chemical labeling, imaging, and other theranostic applications. This abstract is intended as a scanning tool for purposes of searching in the particular art and is not intended to be limiting of the present disclosure.

This paper reports the first examples of ground state radical-mediated intramolecular C–H amination to afford 1-methyl-1,2,3,4-tetrahydroquinolines from N-2,4-dinitrophenoxy derivatives of arylpropylamines. Whereas the photoactivation of N-2,4-dinitrophenoxyamines for intermolecular reactions has been established, ground state chemistry provides the desired cyclization products in moderate to excellent
