Unravelling the Atomic Structure of a Metal‐Covalent Organic Framework Assembled from Ruthenium Metalloligands

Advanced Materials, Volume 37, Issue 13, April 2, 2025.
Metal‐covalent organic frameworks (MCOFs) are novel porous materials that exhibit the advantages of covalent and metal‐organic frameworks. However, it is extremely difficult to resolve their atomic structure and better understand their structure‐properties relation. This work utilizes a synergistic combination of advanced microscopy, spectroscopic, and

The no-defect conjecture in cosmic crystallography

, 1996
The topology of space is usually assumed simply connected, but could be multi-connected. We review in the latter case the possibility that topological defects arising at high energy phase transitions might still be present and find that either they are ...

Quasi-Periodic Crystals—The Long Road from Discovery to Acceptance

Rambam Maimonides Medical Journal, 2013
[Extract] Three surprising discoveries on the nature of matter and its properties were published in the mid-1980s. All these discoveries led to Nobel prizes. The first discovery was in 1985, when fullerenes were discovered by Robert F.

Single‐Crystal Organic Field‐Effect Transistors Based on 5,15‐Bisaryl‐Tetrabenzoporphyrins: Synthesis, Structure, and Charge Transport Properties

Advanced Materials Interfaces, EarlyView.
This study explores single‐crystal organic field‐effect transistors (SC‐OFETs) based on 5,15‐bisaryl‐tetrabenzoporphyrin derivatives. It highlights the impact of meso‐substituted groups on molecular packing and charge transport. Among the derivatives, C8Ph‐BP achieves the highest hole mobility (1.64 cm2 V−¹ s−¹) due to enhanced π‐stacking with ...
