The n-p transition of the lattice-framework silylene 2,3,4,6,7,8-hexa-tert- butyl-1,5-disilatricyclo[4.2.0.01,4]octa-2,7-diene-5,5-diyl was observed by differential transmission spectroscopy at 764 nm. The significantly red-shifted n-p transition of the silylene is caused by the planar four-membered Si2C2 ring containing the divalent silicon atom.
