Helical Single Crystals of Porous Hydrogen‐Bonded Organic Frameworks as a Candidate for Morphologically Functional Organic Materials

open access: yesAngewandte Chemie, EarlyView.
Helical‐shaped crystals of a hydrogen‐bonded organic framework (HOF) with permanent porosity have been developed. The helical HOF shows expansion and contraction, respectively, upon desorption and adsorption of solvents. Moreover, doping of additive molecules can modulate the photophysical properties and morphology of the helical HOF, showing the ...

Dopant‐Tailored Matrices: A Crystal Engineering Strategy for Organic Room‐Temperature Phosphorescent Host–Guest Systems and Beyond

open access: yesAngewandte Chemie, EarlyView.
Rather than selecting dopants to match a pre‐existing host matrix, the dopant‐tailored matrix strategy involves rational engineering of host matrices around a preselected class of dopants by targeting matrix packing motifs that promote synergistic host‐dopant interactions upon doping.

NHC‐Copper(I)‐Mediated Functionalization of White Phosphorus

open access: yesAngewandte Chemie, EarlyView.
White phosphorus is functionalized by N‐heterocyclic carbene supported copper(I) complexes through redox‐neutral steps. Treatment of the resulting complexes with electrophiles releases the ligands from the metal center as asymmetrically substituted organophosphorus butterfly compounds.

Dialkyl Ethers and Sacrificial Zinc: Oxide Synthons for Calcium tert‐Butoxide Formation

open access: yesAngewandte Chemie, EarlyView.
When treated with dialkyl ethers, [(BDI)Ca‐μ‐H‐Zn(t‐Bu)2(η6‐C7H8)] (BDI = HC{C(Me)NDipp}2 initiates a sequence of twofold ether dealkylation and oxide sequestration as tert‐butoxide in a process predicated on a combination of extreme basicity and a cooperative redox process administered by the dissimilar constituent metals.
