A thienopyrrole oligomer conjoined to DNA was prepared by means of a templated synthesis protocol. The oligomer was formed by reaction, initiated with HRP/H2O2, of thieno[3,2-b]pyrrole monomers attached to cytosine bases. The thienopyrrole oligomer was characterized spectroscopically.

In this study, we report a detailed spectroscopic study concerning the energy levels and vibrational structure of thiophene-pyrrole-containing S,N-heteroacenes. The aim of the study is first, to understand the differences in the photoluminescence (PL) efficiencies in this structurally similar series and second, to compare the electronic structure of S,N-heteroacenes to that of linear acenes and phenacenes, with a view to derive guidelines for the design of singlet fission materials. For S,N-heteroacenes comprising seven fused heterocyclic rings, we observe a higher PL quantum yield for derivatives with terminal thienothiophene units than for thienopyrrole-capped ones.
