Electronic delocalization (conjugation) is for the application of organic materials in electronic, photonic, and optoelectronic devices.1 The presence of weakly localized electron density affects the electron energy by electric or magnetic fields and/or interaction with photons. In that way, electronic
(e.g., transistors), photonic (e.g., photographic plates), or optoelectronic (e.g., light-emitting diodes) devices could be developed. Among conjugated materials, there are transparent polymers, doped with low-molecular-weight photochromic dyes, and conjugated polymers, which exhibit electronic conductivity. In the present chapter, the use of combinatorial chemistry techniques to find photochromic dyes and modified conducting polymers, will be described.
