TLDR
Experimental and theoretical analyses indicated that the dihedral angle of the two naphthalene rings is strongly coupled to the azobenzene photoisomerization; cis-azobenzenes induces a transoid-binaphthyl structure, while trans-azabenzene induces a cisoid- binaph fourthyl structure.About:

Binaphthyl-Bipyridyl Cyclic Dyads as a Chiroptical Switch.
TL;DR: A series of chiral cyclic dyads, axially chiral binaphthyls linked to a 3,3'-bipyridyl, was synthesized, and Regioisomer 4 exhibited a dextro/ levo rotation switching ability in [α]D.

Zn2+-induced conformational changes in a binaphthyl-pyrene derivative monitored by using fluorescence and CD spectroscopy
Fang Wang,Fang Wang,Jong Hun Moon,Raju Nandhakumar,Raju Nandhakumar,Baotao Kang,Dabin Kim,Kwan Mook Kim,Jin Yong Lee,Juyoung Yoon +9 more
TL;DR: A unique binaphthyl-pyrene system 1 is developed, whose dihedral angle is reversibly modulated by the addition of Zn(2+), whose presence in samples can be readily monitored by employing CD and fluorescence spectroscopy.

Are two azo groups better than one? Investigating the photoresponse of polymer-bisazobenzene complexes
Jaana Vapaavuori,Jaana Vapaavuori,Alexis Goulet-Hanssens,Ismo T. S. Heikkinen,Christopher J. Barrett,Arri Priimagi +5 more
TL;DR: In this article, the authors show that using bisazochromophores instead of the more common mono-azobenzene derivatives makes a difference in the performance of light-responsive azopolymers, more specifically in photo-orientation and all-optical surface patterning.

Control of circularly polarized photoluminescent property via dihedral angle of binaphthyl derivatives
TL;DR: In this paper, the chiroptical signs in circularly polarized luminescence (CPL) and circular dichroism spectra of chiral binaphthyl fluorophores in solution were found to be controllable by changing the dihedral angle of the unit regardless of the same axial chirality.

Fully optimized contracted Gaussian basis sets for atoms Li to Kr
TL;DR: In this article, various contracted Gaussian basis sets for atoms up to Kr are presented which have been determined by optimizing atomic self-consistent field ground state energies with respect to all basis set parameters, i.e., orbital exponents and contraction coefficients.

Fully optimized contracted Gaussian basis sets of triple zeta valence quality for atoms Li to Kr
TL;DR: In this article, a triple zeta valence (TZV) basis set is presented for Li to Kr. The TZV bases are characterized by typically including a single contraction to describe inner shells and three basis functions for valence shells.

TL;DR: The purpose of this review is to broadly survey the mechanical to chemical relationships between synthetic polymers, and to consider the I-O relationship as an energy transduction process for designing stimuli-responsive materials.
