Photoinduced intramolecular charge-transfer fluorescence occurs in (4-N,N-dimethylaminophenyl)(4′-cyanophenyl)-(1) and (4-methoxyphenyl)(4′-cyanophenyl) dimethylsilane (2); the X-ray structure of 1 shows that the donor and acceptor chromophores are positioned orthogonally, hence, charge transfer is mediated via the –SiMe2–spacer.
