Starting from Heptcyclo[6.6.0.02.6.03.13.04.11.05.9.010.14]tetradecane, we were able to synthesize donor-bridge-acceptor substituted derivatives by condensation reaction. The components for the condensations were malonitrile and ethyl cyanoacetate for the acceptor part, and benzyltriphenylphosphate (7), [(naphthalene-1-yl)methyl]- triphenylphosphate (8), and[(anthracen-9-yl)methyl]triphenylphosphate (9). To condense malonitrile and ethyl cyanoacetate we used the Knoevenagel condensation and for the phosphates we used the Wittig reaction procedure. Fluorescence spectra provided evidence for efficient photoinduce electron transfer in only the benzene and naphthalene derivatives, but not in the analogous anthracene derivative.
