Field Effects Induce Bathochromic Shifts in Xanthene Dyes
摘要:
There is ongoing interest in near-infrared (NIR) absorbing and emitting dyes for a variety of biomedical and materials applications. Simple and efficient synthetic procedures enable the judicious tuning of through-space polar (field) effects as well as low barrier hydrogen bonding to modulate the HOMO-LUMO gap in xanthene dyes. This affords unique NIR-absorbing xanthene chromophores.

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 (I). At least one of R1/R2, R2/R3, R3/R4, R5/R6, R6/R7, and/or R7/R8 together forms substituted or unsubstituted cycloalkyl or aryl.
