Abstract:
Rylene imide dyes have been among the most promising organic semiconducting materials for several years due to their remarkable optoelectronic properties and high chemical/thermal stability. In the past decades, various excellent rylene imide dyes have been developed for optoelectronic devices, such as organic solar cells (OSCs) and organic field-effect transistors (OFETs). Recently, tremendous progress of perylene diimides (PDIs) and their analogues for use in OSCs has been achieved, which can be attributed to their ease of functionalization. In this review, we will mainly focus on the synthetic strategies toward to latest PDI dyes and higher rylene imide analogues. A variety of compounds synthesized from different building blocks are summarized, and some properties and applications are discussed.

Preparation of Amides
The DCC-promoted synthesis of amides begins with the protonation of DCC by carboxylic acid. The protonation makes it a better acceptor. Next, the addition of carboxylate to the protonated carbodiimide gives a reactive acylating agent.
Subsequently, the amine acts as a nucleophile that attacks the acylating agent to form a tetrahedral intermediate. In the...

Structure of Conjugated Dienes
Conjugated dienes are compounds characterized by the presence of alternating double and single bonds. In a conjugated system like 1,3-butadiene, the unhybridized 2p orbital on each carbon overlaps continuously, allowing the π electrons to be delocalized across the entire molecule. In contrast, this type of overlap does not occur in cumulated and isolated dienes, such as 2,3-pentadiene and 1,4-pentadiene, respectively. Instead, the π electrons remain localized between the double...
