Self‐Assembled Gelators for Organic Electronics

Nature excels at engineering materials by using the principles of chemical synthesis and molecular self-assembly with the help of noncovalent forces. Learning from these phenomena, scientists have been able to create a variety of self-assembled artificial materials of different size, shapes, and properties for wide ranging applications. An area of great interest in this regard is solvent-assisted gel formation with functional organic molecules, thus leading to one-dimensional fibers. Such fibers have improved electronic properties and are potential soft materials for organic electronic devices, particularly in bulk heterojunction solar cells. Described herein is how molecular self-assembly, which was originally proposed as a simple laboratory curiosity, has helped the evolution of a variety of soft functional materials useful for advanced electronic devices such as organic field-effect transistors and organic solar cells. Highlights on some of the recent developments are discussed.

In the first part of the review the selected examples of title rotaxanes are shown, among them those containing thiophene and acridane units, as well as those of the dendrimeric structure. In the second part the rotaxanes with electrostatic or steric barriers, incorporated for increase of lifetime of their metastable state, are presented. The third part of the review deals with rotaxanes investigated in the aspect of their secondary structure, and in the fourth part rotaxanes containing a modified tetracationic cyclophane ring are described.

“…23,24 However, TTF-based gelators with cholesterol groups are scarcely described. Stoddart et al 25 have just recently reported TTF-based rotaxane with cholesterol groups and the resulting organogels. Herein we want to report a new TTF derivative with two cholesterol groups (compound 1 in Scheme 1).…”

A new tetrathiafulvalene (TTF) derivative with two cholesterol units (compound 1) was synthesized and characterized. Gelation of n-hexane occurred after the hot solution of 1 was subjected to ultrasonic treatment for a few minutes. The resulting organogel was characterized with SEM, XRD and AFM. Besides heating the gel-sol transition also occurred upon addition of I 2 which can oxidize the TTF unit in 1. This result provides a new example of organogels responding to redox reactions. Interestingly, gelation-induced CD signals were observed and the CD signals can be tuned with the gel-sol transition which can be effected by heating and chemical reaction with I 2 .
