“…Various fullerene[C 70 ] microcrystals are prepared. Previous works have reported that the good/poor solvent ratio and concentration can mediate the morphology of fullerene microcrystals [3a] . Therefore, we adjust the two factors to further study their important effects on the morphology evolution of C 70 assemblies.…”

Controlled crystallization of fullerene molecules into ordered molecular assemblies is important for their applications. However, the morphology engineering of fullerene[C 70 ] assemblies is challenging, and complicated architectures have rarely been reported due to the low molecular symmetry of C 70 molecules, which makes their crystallization difficult to control and the low production yield as well. Herein, with the assistance of solvent intercalation, a general reprecipitation approach is reported to prepare morphologically controllable C 70 microcrystals with mesitylene as a good solvent and npropanol as a poor solvent in one solvent system without replacing specific solvents. A series of C 70 microcrystals with high uniformity from perfect cubes and defective hoppers to novel cruciform-pillars are obtained by intentionally tuning C 70 concentration and the volume ratio of mesitylene to n-propanol. Among them, novel cruciform-pillar-shaped microcrystals are obtained for the first time by further decreasing the amount of mesitylene in the solvent-intercalated microcrystals. Notably, the C 70 concentration is a key parameter for the selective growth of C 70 hopper, rather than the volume ratio of mesitylene to n-propanol. Interestingly, the hoppershaped microcrystals exhibit excellent photoluminescence properties relative to those of cubes and cruciform-pillars owing to the enhanced light absorption, proving their potential applications in optoelectronic devices. This study offers new insights into the morphology-controlled synthesis of other micro/nanostructured organic microcrystals and the fine tuning of photoluminescence properties of organic crystals.

“…The tight p-p packingb e-tween fullerene molecules results in the robust architectures of the FCNFs.

The SEM images in Figure1b2 and Figure S1 dr eveal that the high-temperature treatment only causedn egligible distortions to the fibrousf eature except for the rough surface, leaving the film structure totally unchanged, which suggests the good mechanical stability of these fullerene-derived fibers.…”

“…The high‐resolution TEM (HRTEM) image of FCNFs (Figure 1 a4) displays a clear crystalline feature with the lattice spacing of 1.15 nm, confirming that the FCNFs are composed of stacked C 60 molecules. The tight π–π packing between fullerene molecules results in the robust architectures of the FCNFs [16] . Interestingly, after the high‐temperature pyrolysis of FCNFs in the presence of ammonia and sublimed sulfur, the robust film morphology is completely maintained in the N,S‐PCNFs, though the color changed from brown to black (Figure 1 b1).…”

The development of highly efficient metal-free electrocatalysts for the oxygen reduction reaction(ORR) has attracted great attention for the creationo fe lectrochemical energy devices.I nt his study,o ne-dimensional (1 D) fullerene nanofibers prepared from liquid-liquidi nterfacial precipitation are first fabricated into fullerene-derived carbon nanofiber films (FCNFs)t hrough as imple filtration procedure. Then, pyrolysis of the FCNFs in the presence of ammonia and sulfur produces N-and S-co-dopedporous carbon nanofiber films (N,S-PCNFs). As excellent metal-free electrocatalysts for the ORR, N,S-PCNFs exhibit remarkable catalytic activity,s uperiors tability,a nd excellent methanolt olerance in both alkaline anda cidic solution. Such ah igh ORR performance benefits from the robust porous nanofiber network structurew ith high concentrations of active N-andSgroups and abundantd efects. Notably,u pon practical use of N,S-PCNFs as catalysts in Zn-air batteries, ah igh powerd ensity and al arge operating voltage are achieved, with ap erformance comparable to that of the commercialP t/C catalyst. This work presents af acile strategy for the creation of a new class of energy nanomaterials based on fullerenes, demonstrating their practical uses in electrocatalytic ORR processes and Zn-air batteries.

“…As shown in Fig. 1, fullerene C 60 has a precise structure with abundant unsaturated bonds that can be easily functionalized to produce various derivatives, which could effectively decrease the structural/componential heterogeneity issue that troubles many carbon materials [40][41][42]. Moreover, pristine fullerenes are highly soluble in many organic solvents (carbon disulfide, benzene, toluene, etc.…”
