pH indicating resins were prepared by covalently attaching carboxylic acid derivatives of sulfthalein dyes, synthesized using a Suzuki cross-coupling, onto resin beads. The resin-bound indicators showed the expected colour changes according to pH and their behaviour was analysed using a micro UV/Vis spectrometer.

Self-indicating methylisocyanate resin, which functions as both a scavenger and an indicator for amines, was used for in-situ reaction monitoring and purification of a urea based library.

Polystyrene-poly(ethylene glycol) resin-captured cross-linked palladium nanopaticles were prepared via a straightforward route, and their heterogeneous behavior was truly confirmed by various tests. They were applied to aqueous Suzuki cross-coupling reactions with various aryl bromides and recycled up to six times without loss of activity.
