Graphical Abstract

The blue/orange dual fluorescence properties of tetramesityldiborane(4) are reported by Yoshiaki Shoji, Yasuhiro Ikabata et al. in their Research Article (e202113549). Theoretical calculations showed that the diborane(4) in the S1 state adopts a twisted or planar geometry, which is responsible for the blue or orange fluorescence, respectively. The relative intensity of the dual fluorescence is sensitive to the viscosity of the medium, highlighting the potential of the diborane(4) as a ratiometric viscosity sensor.

Proteins

In their Communication (e202109961), Martin Blackledge et al. report the self-assembly of intrinsically disordered tardigrade proteins into fibrous gels in response to environmental stress.

Foldamers

In their Research Article (e202108364), Sunbum Kwon, Hee-Seung Lee et al. report on the conformational adaptation of β-peptide foldamers for the formation of metal–peptide frameworks.

Prebiotic Chemistry

Phosphorylation chemistry facilitating the synthesis of closely related nucleotides and nucleoside triphosphates that are compatible with abiotic oligomerization is reported by Ulrich F. Müller, Ramanarayanan Krishnamurthy et al. in their Research Article (e202113625).

DNA Nanotechnology

In their Research Article (e202111647), Hang Xing et al. present a liposome fusion-based transport strategy that enables the incorporation of a variety of functional moieties onto both external and internal cell membrane surfaces.
