polarizability and electronic transparency of the utilized π-linker. The absorption maxima of target chromophores were found within the range of 346 – 412 nm and the emission maxima of emissive derivatives were found within the range of 411 – 499 nm. Novel TFBs were compared with TFBs previously described in the literature. The experimental data are further corroborated by theoretical calculations.
