Abstract

The (α-NR,α′-NR,N,N′-(C6H4C[triple bond, length as m-dash]CSiMe3)4)[Q] models ([Q] = –N[double bond, length as m-dash]C6H4[double bond, length as m-dash]N–) exhibit upper excited state emissions Sn,Tn → S0 (n >1, R = Boc), similar to emeraldine, vs. a fluorescence S1 → S0 (R = H), driven by a large change in dihedral angles made by the NR–C6H4 and [Q] planes and intramolecular H-bonds.
