title: Halochromism and protonation-induced assembly of a benzo[g]indolo[2,3-b]quinoxaline derivative.
abstract: A new halochromic compound is reported with pronounced UV/Vis spectral responses that depend on the extent of protonation and on the counter-ion structure. The absorption can be controlled over the entire visible spectrum and into the near-IR via a protonation-induced assembly mechanism. Thin-films were used for colorimetric detection of acid vapors.
