Rare‐Earth Multivariate Metal–Organic Frameworks: Cationic Radius Biased Compositional Control and Property Tuning

open access: yesAngewandte Chemie, EarlyView.
A family of multivariate metal–organic frameworks, UoB‐116(Ln), can be prepared using up to 16 different metals, revealing the ability to tune properties through compositional control. ABSTRACT The synthesis of a multivariate metal–organic framework (MTV‐MOF) family, [Ln(DNNDI)1.5]n (UoB‐116), is reported (DNNDI: N,N'‐bis(dinicotinate)‐1,4,5,8 ...

Axially Chiral Nonalternant Polycyclic Aromatic Hydrocarbon With Consecutive Pentagons Exhibiting Large Spin‐Polarized Current

open access: yesAngewandte Chemie, EarlyView.
Here we report two nonalternant polycyclic aromatic hydrocarbons (PAH) (1 and 2), which contain two and four consecutive pentagons, respectively. Under acidic conditions, 1 and 2 dimerize to afford the axially chiral dimers AC1 and AC2. The central azulene moiety in both 2 and AC2 shows an unusually short transannular bond of 1.366 Å.
