Zusammenfassung:	A composite material suitable for use in sensing and catalysis applications with conjugated polymers non-covalently bound to the carbon nanotubes. The conjugated polymers have alternating aromatic (Ar) units and bipyridine (BPy) units. Metal nanoparticles having a size that is between about 0.3 nm and about 5 nm are bound to the conjugated polymers at respective BPy units, thereby anchoring the metal nanoparticles to the carbon nanotubes. Thus, a metal salt solution was added into the polymer/carbon nanotube solution to form a metal-BPy complex, which is in situ photo reduced to metal nanoparticles. Therefore, the formed nanoparticles are tightly anchored to the nanotube and can be self-regenerated by room light to offer the material a high performance and durability.
