Synthesis and properties of molecular rods. 2. Zig-zag rods

Article Abstract:

Oligomers are of interest as short chain models for specialty polymers and numerous oligomers were prepared as functional building blocks for nanoscale architectures with specific and tunable properties. It is shown that even small changes at the periphery of the oligomers, perhaps only introduced to improve solubility and processability of the longer rods, can have a profound impact on electronic properties, rendering comparisons difficult.

Artificial molecular rotors

Article Abstract:

Man-made molecular rotors are discussed form the point of view of their potential utility for 'molecular machinery'. A gradual shift of emphasis of studies of rotor molecules floating freely in solution to systems is expected in which they are mounted on the surfaces or inside solids.

Bicyclo[1.1.1]pentanes, [n[staffanes, [1.1.1]propellanes, and tricyclo[2.1.0.0(super 2,5)]pentanes

Article Abstract:

A detailed review of research focusing on all compounds containing the bicyclo[1.1.1]pentane skeleton and published in the period to mid-1999 is presented. It is suggested that application-oriented work is now being undertaken on [1.1.1]propellanes and bicyclo[1.1.1]pentanes.
