Diketopyrrolopyrrole-tellurophene polymer for fast, selective, and reversible detection of bromine in solution, vapor, and solid states: A systematic study

Sequence-controlled alternating block polychalcogenophenes: synthesis, structural characterization, molecular properties, and transistors for bromine detection

“…58–61 In particular, previous studies conducted by Seferos et al and others have demonstrated that small molecules and conjugated polymers incorporating tellurophene units can undergo bromine addition at the tellurium (Te) center. 62–67 However, bromine addition for tellurophene-incorporated polychalcogenophenes in an alternating fashion and the resulting properties have never been explored. STePh 2 , a monomer containing a single (3-hexylthiophene-3-hexyltellurophene) unit, was designed and synthesized as a reference compound for carefully studying the bromine coordination (Fig.…”
