Solubility Enhancing Reagents [Material Building Blocks]
Alkyl groups do not affect molecular electronic properties, because they do not strongly interact with π-conjugates. However, the effect of alkyl groups is large in the molecule-assembled solid state, modifying solubility and melting point when alkyl groups are introduced. In particular, organic devices require alkyl derivatizations to increase solubility, because solution-processible printing technologies are required for large scale manufacturing. In addition, introduction of a long alkyl chain to an organic molecule produces a liquid crystal material.
