Synthetic chemistry is the enabling science for organic electronic and redox active materials, while the processing methods employed provide control of the nature of electrode/material interfaces and the morphology of the active material itself. We will discuss electron-rich (donor type), electron-poor (acceptor type), and donor-acceptor polymers as electrochromic, charge transport and organic solar cell materials. We compare the use of spin-coating, slot-die coating and spray-coating in preparing materials and devices for field effect transistors, molecular- and polymer-based bulk heterojunction solar cells, along with electrochromic windows and displays. In some instances, the use of processing additives controls the rate with which a material morphology develops and can be instrumental in enhancing performance. High contrast electrochromic polymers are effectively processed to open morphology films using ultrasonic spray coating. Interface control in polymer solar cells, allow dithienosilole- and dithienogermole-based polymers cells to attain EQE's of ~70% from 400 to 700 nm and PCEs ranging from 7.0 to 8.5%.
