TLDR
A photoresponsive orthogonal supramolecular system is developed by combining the UV-light-responsive Azo/α-CD and green- light-responsive ipAzo/γ-CD host-guest complexes, which forms a strong host-Guest complex with γ-cyclo dextrin whereas trans-ipAzo binds weakly.Abstract:
We synthesized a novel green-light-responsive tetra-ortho-isopropoxy-substituted azobenzene (ipAzo). Cis-ipAzo forms a strong host-guest complex with γ-cyclo dextrin (γ-CD) whereas trans-ipAzo binds weakly. This new photoresponsive host-guest interaction is reverse to the well-known azobenzene (Azo)/α-cyclodextrin (α-CD) complex, which is strong only between trans-Azo and α-CD. By combining the UV-light-responsive Azo/α-CD and green-light-responsive ipAzo/γ-CD host-guest complexes, a photoresponsive orthogonal supramolecular system is developed.read more

Synthesis of a tetrasubstituted arylphosphonate via the anionic phospho-Fries rearrangement
TL;DR: In this paper, the anionic phospho-Fries rearrangement of phosphoric acid (3,5-di-isopropoxy)phenyl ester diethyl esters (11 ) gave rise to (2-hydroxy-4,6-di isopropoxoxy-phenyl)phosphonic acid (12) in excellent yield, which was converted to the corresponding triflate which was coupled with vinyltributylstannane, under Stille conditions, to give a styrene.
