The Role of Photoisomerisation on the Photodetachment of the Photoactive Yellow Protein Chromophore.

The photocycle of photoactive yellow protein (PYP) is initiated by a photoinduced trans-cis isomerisation around a C=C bond in the chromophore that lies at the heart of the protein; however, in addition to the desired photochemical pathway, the chromophore can undergo competing electronic relaxation processes. Here, we combine gas-phase anion photoelectron spectroscopy and quantum chemistry calcul...

A Concave-Convex π-π Template Approach Enables the Synthesis of 10Cycloparaphenylene-Fullerene 2Rotaxanes.

The cycloparaphenylenes (CPPs) are a class of strained macrocycles that until recently were considered beyond the reach of organic synthesis. With its cyclic array of ten para-substituted phenylene rings, [10]CPP possesses a concave π-system that is perfectly preorganized for the strong supramolecular association of convex fullerenes such as C60. Although mechanically interlocked CPP architecture...
