Template directed photodimerization of trans-1,2-bis(n-pyridyl)ethylenes and stilbazoles in water

Abstract
Template induced photodimerization of trans-1,2-bis(n-pyridyl)ethylene dihydrochlorides and trans-n-stilbazole hydrochlorides within cucurbit[8]uril in aqueous media leads to high yields of the syn dimer.
