Time-resolved Studies of 1,3,6-Substituted Fulvenes

Fulvene-based compounds are of interest as accepting moieties in donor-acceptor organic molecules for molecular electronic materials. The photophysical and electrochemical properties of these compounds have been shown to be highly tunable depending on the fulvene ring substitution$^{\mathrm{1,2}}$. We report steady-state absorption and emission measurements along with emission lifetimes for a series of 1,3,6-substitued fulvene compounds. A better understanding of the excited-state dynamics of these compounds can guide the development of compounds optimized for use in donor-acceptor organic molecules and other applications. $^{\mathrm{1}}$A.J.
