DESCRIPTION:In the past decade\, significant progress has been made in the
  fabrication of organic semiconductor thin-film devices predominantly due 
 to important improvements of existing materials and the creation of a weal
 th of novel compounds. Many challenges\, however\, still exist. Key to com
 mercial success is to make it technological practice to exploit the touted
  potential for low-cost manufacturing of these functional materials. This 
 requires intimate knowledge of relevant structure/processing/performance i
 nterrelations. Here\, examples are given of how polymer processing ‘tool
 s’ may be utilized to gain further understanding of this interesting cla
 ss of materials and how the physical organization\, from the molecular to 
 the macro-scale of functional organic matter such as polymer semiconductor
 s can can be controlled. To this end\, we present a survey on the principl
 es of structure development from the liquid phase of this material family 
 with focus on how to manipulate their phase transformations and solid-stat
 e order to tailor and tune the final ‘morphology’ towards technologica
 l and practical applications.
