中文摘要	different core moieties can modulate the self-assembly behaviors of second generation carbazole-based conjugated dendrimers with the same dendrons and surface groups in a solvent mixture of a good solvent and an anti-solvent. for ta-d2 with triphenylamine as the core, crystalline spherulites were formed since the more planar molecular configuration of ta-d2 can enhance the pi-pi interactions between the carbazole dendrimers. for g2 with the large-sized fac-ir(pbi)(3) as the core, amorphous globular particles were obtained because the large core in g2 increases the distance between carbazole dendrimers and decreases the pi-pi interactions. while for tpo-d2 with triphenylphosphine oxide as the core with moderate size and a twisted molecular configuration, a supramolecular gel consisting of fibers was formed in the solvent mixture of aromatic solvent and alcohol solvent. the sol-gel conversion of tpo-d2 can be observed by simple heating and cooling. fast cooling and ultrasonication are beneficial to get uniform tpo-d2 gel with small aggregates. the tpo-d2 xerogel shows three-dimensional networks with the nanofibers entangling and intersecting with each other. the moderate pi-pi interactions between the carbazole units modulated by the core may be the driving force for tpo-d2 to form the gel, the balance phase between the ordered crystal and amorphous precipitate.
