Twelve-membered B2Si4O6 borasiloxane macrocycles

Second-order nonlinear optical properties of eight-membered centrosymmetric cyclic borasiloxanes

SHG efficiencies of eight-membered centrosymmetric cyclic borasiloxanes arise form distorted silicon atom, strong electron withdrawing group and non-covalent interactions in crystal packing.

In situ generated polysiloxanes stabilizing μ3-oxo bridged Sb3 triangles

The reaction of RSbO3H2 with t-butylsilanetriol has led to the isolation of organoantimony(v) based molecular triangles stabilized by siloxane frameworks. Depending on the reaction conditions employed or the substituents present on the antimony atom, either a combination of a disiloxane and a tetrasiloxane framework or a trisiloxane framework was generated in situ leading to the stabilization of the Sb3 triangle.

Eight membered cyclic-borasiloxanes: synthesis, structural, photophysical, steric strain and DFT calculations

A series of eight membered cyclic borasiloxanes were synthesized and structurally characterized. The photophysical properties were investigated. HOMO–LUMO, hyperpolarizability and steric strain were computed by B3LYP/6-31+G** method.
