Synthesis of Rhodamines from Fluoresceins Using Pd-Catalyzed C–N Cross-Coupling [PDF]

Organic Letters, 2011
A unified, convenient, and efficient strategy for the preparation of rhodamines and N,N′-diacylated rhodamines has been developed. Fluorescein ditriflates were found to undergo palladium-catalyzed C–N cross-coupling with amines, amides, carbamates, and ...

Mechanically switchable polymer fibers for sensing in biological conditions [PDF]

, 2016
The area of in vivo sensing using optical fibers commonly uses materials such as silica and polymethyl methacrylate, both of which possess much higher modulus than human tissue. The mechanical mismatch between materials and living tissue has been seen to
