Dimensionality is a fundamental parameter to modulate the properties of solid materials by tuning electronic structures. Covalent organic frameworks (COFs) are a prominent class of porous crystalline materials, but the study of dimensional dependence on their physicochemical properties is still lacking. Herein we illustrate photocatalytic performances of N,N-diaryl dihydrophenazine (PN)-based COFs are heavily dependent on the structural dimensionality. Six isostructural imine-bonded 2D-PN COFs and one 3D-PN COF were prepared.

How to Choose the Best Cot For Newborns The cot is the baby's bed until is four years old. Therefore, you want it to be comfy, sturdy and safe. Make sure it is gaps-free mattresses since gaps could pose a suffocation risk for babies. Also look for a cot that is able to convert into an infant bed. Single Cot The OEX Ultralite foldable cot is among the lightest options available. It weighs 2.68kg and is almost a quarter of the price of the Helinox version I tried. It's also much simpler to set-up - th
