Novel fluorophores for single-molecule imaging.
J Am Chem Soc. 2003; (5): 1174-5
Nonlinear optical chromophores based on dicyanodihydrofuran acceptors paired with amine donors have been found to exhibit sufficiently large fluorescence quantum yields and stability to enable single-molecule detection in polymeric hosts. To illustrate the breadth of this class, six fluorophores are presented, spanning the emission range from 505 to 646 nm. In contrast to conventional single-molecule fluorophores, the new molecules feature sensitivity to local rigidity, large ground-state dipole moments, and large polarizability anisotropies, properties that can be used to design new reporter experiments at the single-molecule level.
