An air-stable emissive di(1-naphthyl)disilene protected by the bulky Eind groups (Eind = 1,1,3,3,5,5,7,7-octaethyl-s-hydrindacen-4-yl) has been obtained by the reduction of the corresponding dibromosilane (Eind)(1-Naph)SiBr2 with lithium naphthalenide. The X-ray crystallography shows a highly coplanar (E)-1,2-di(1-naphthyl)disilene skeleton, favorable for the efficient π-conjugation involving the Si=Si unit, together with a distinct CH/π interaction between the peri-H atom of the 1-naphthyl groups and the aromatic ring of the perpendicularly-oriented Eind groups.

2,6-Di(2-pyridyl)benzo[1,2-b:4,5-b′]difuran (2-PyBDF) shows a π–π-stacking packing structure in a single crystal and some intriguing properties: mechanochromism in the solid state, and solvent and concentration dependence of absorption and emission spectra.
