Abstract:
The fusion of bowl-shaped π-conjugated corannulene units to anion-responsive π-conjugated dipyrrolyldiketone-boron complexes resulted in new molecular materials with a unique self-assembly capability. The bowl-fused receptor with aliphatic tails could form both supramolecular gels and mesophases through π-stacking interactions and also exhibited anion-responsive characteristics. The presence of the π-bowl unit not only afforded enhanced self-assembly capability both in solution and in the mesophases, as evidenced by gelation experiments and phase-transition profiles, but also enhanced intrinsic charge-carrier mobility.

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...
