The introduction of a five-membered ring into hexagon-fused networks typically induces strain that causes positive Gaussian curvature, leading to bowl-shaped polycyclic aromatic hydrocarbons (PAHs), often referred to as buckybowls or π-bowls. The interest in buckybowls is derived from their intriguing properties including, but not limited to, pyramidalized sp2 carbon atoms, low-lying lowest unoccupied molecular orbital (LUMO), surface charge stabilization, and bowl-to-bowl inversion. In recent years, investigations into the functionalization of buckybowls, as well as the structural aspects related to properties, have made significant progress. Indeed, the functionalization of buckybowls is a major route to increase structural diversity and fine-tune their properties. In particular, the fusion of aromatic rings to buckybowl rims (π-extension of buckybowls) has established a particularly promising synthetic strategy to access a wide range of buckybowl-based nanostructures with unique topologies and properties. A major obstacle, however, is the limited number of appropriate buckybowls, which could be suggested as potential frameworks for further functionalization. Moreover, buckybowls have been typically synthesized by ring-closing reactions, but many of these procedures suffer from the occurrence of considerable strain and lead to an undesired rearrangement. As a result, the development of buckybowl-based nanocarbons with desirable properties is still in its infancy due to the limited structural diversity, functionalization, and scalability.

基于 Buckybowl 的纳米碳：合成、性质和应用
将五元环引入六边形熔融网络通常会诱导应变，导致正高斯曲率，从而导致碗状多环芳烃 （PAH），通常称为布基碗或π碗。对 buckybowls 的兴趣源于其有趣的特性，包括但不限于金字塔化的 sp2 碳原子、低位最低未占据分子轨道 （LUMO）、表面电荷稳定和碗到碗的反转。近年来，对 buckybowls 的功能化以及与性能相关的结构方面的研究取得了重大进展。事实上，buckybowls 的功能化是增加结构多样性和微调其特性的主要途径。特别是，芳香环与 buckybowl 边缘的融合（buckybowls 的π延伸）建立了一种特别有前途的合成策略，以获得具有独特拓扑和特性的各种基于 buckybowl 的纳米结构。然而，一个主要障碍是合适的 buckybowl 数量有限，这可以被认为是进一步功能化的潜在框架。此外，buckybowls 通常是通过闭环反应合成的，但其中许多程序都会产生相当大的应变并导致不希望的重排。因此，由于结构多样性、功能化和可扩展性有限，具有理想特性的基于 buckybowl 的纳米碳的开发仍处于起步阶段。
