The synthesis and photochemical behavior of several members of the bis(n.1)metacyclophanylidene series are presented. The properties of these compounds are compared to a model compound, tetra-3-tolylethylene. The photophysical properties of the tethered tetraphenylethylenes change dramatically with the length of hydrocarbon tethers connecting the gem-phenyl rings. From these changes in photophysical properties and analysis of ground-water structures and properties, they propose that phenyl ring torsional motion plays a significant, if not primary, role in the photochemical of tetraphenylethylenes.
