Currently there is intense scientific and technological interest in molecular materials as diverse as quasi-one-dimensional organic crystals [1] and amorphous organic polymers [2, 3]. Despite this diversity they pose several common scientific issues that indicate potentially useful and important technological properties. They also offer opportunities for studying scientific questions characteristic of their particular genre. Through this predictive understanding, the possibility of marrying the best features of each is a strong motivator for the intense activity in these fields. A particularly interesting combination of such features exists in disordered organic solids to which the large and important class, polymers, belongs.
