enable researchers and clinicians to visualize biological events in living cells, tissues, and organs in real time. Herein, the focus is on the structure and properties of the relatively rare benzo[ a]xanthenes that exhibit enhanced steric and electronic interactions due to their annulated structures. Three types of fluorophores were synthesized: (i) pH- and solvent-dependent seminaphthorhodafluors, (ii)
common fluorophores. By simply appending a 1,4-diethyl-decahydro-quinoxaline (DQ) moiety onto the conjugated structure, we introduced a vibronic backbone that could facilely expand the Stokes shifts, emission wavelength, and photostability of 11 different fluorophores by more than 3-fold. This generalizable method could significantly improve the imaging efficiency of commercial fluorophores. As a demonstration

Embodiments of near-infrared (NIR) dyes are disclosed, along with methods and kits for detecting analytes with the NIR dyes. The NIR dyes have a structure according to the general structure
At least one of R1/R2, R2/R3, R3/R4, R5/R6, R6/R7, and/or R7/R8 together forms a substituted or unsubstituted cycloalkyl or aryl.

Molecular probes for detecting and imaging pancreatic cancer are disclosed. The probes are modified benzoxanthene fluorophores, which are selectively taken up by pancreatic cancer cells, such as pancreatic ductal adenocarcinoma cells. Embodiments of the disclosed probes are useful for pancreatic cancer detection, therapeutic monitoring, and/or image-guided surgery.
