Three-Dimensional Fully Conjugated Carbaporphyrin Cage

open access: yesJournal of the American Chemical Society, 2018
A fully conjugated three-dimensional (3D) expanded carbaporphyrin (2) was prepared in a one-pot procedure that involves a [2+4] condensation reaction between a dibenzo[ g, p]chrysene-bearing tetrapyrrole precursor (1) and pentafluorobenzaldehyde, followed by oxidation.

Aromaticity in Fully π-Conjugated Multicyclic Macrocycles

open access: yesJournal of the American Chemical Society, 2023
The research on aromaticity has mainly focused on monocyclic [n]annulene-like systems or polycyclic aromatic hydrocarbons. For fully π-conjugated multicyclic macrocycles (MMCs), the electronic coupling between the individual constitutional macrocycles would lead to unique electronic structures and aromaticity.

Linear fully conjugated meso-aryl pentapyrrins

open access: yesTetrahedron Letters, 2009
A meso-2,6-dichlorophenyl pentapyrrin was prepared using a modified method for dipyrrane synthesis followed by simple DDQ oxidation. The fully conjugated structures formed via redox inter-conversions were studied using crystallographic as well as observed and calculated spectral data.

Aromaticity in Fully π-Conjugated Open-Cage Molecules

open access: yesJournal of the American Chemical Society, 2022
Although aromaticity in 2D π-conjugated monocyclic and polycyclic molecules has been intensively studied, aromaticity in 3D fully π-conjugated molecular cages remains largely unexplored mainly due to the synthetic challenges. Herein, we report the facile synthesis of a π-conjugated molecular cage (1) containing four dimethylmethylene-bridged ...

A Fully Conjugated 3D Covalent Organic Framework Exhibiting Band‐like Transport with Ultrahigh Electron Mobility

open access: yesAngewandte Chemie - International Edition, 2021
Although pi-conjugated two dimensional (2D) covalent organic frameworks (COFs) have been extensively reported, developing fully pi-conjugated 3D COFs is still an extremely difficult problem due to the lack of fully pi-conjugated 3D linkers. We synthesize
