Dithizone and its derivatives and complexes are, to our knowledge, probably the most \u201ccolorful\u201d compound, being responsive to no less than seven different external stimuli that effect color change. Apart from a more detailed discussion of the cyclic voltammetry and observed electrochromism in the SCH3-substituted free ligand and mercury complex, concentratochromism, solvatochromism, halochromism, thermochromism, and chronochromism in the ligand, and photochromism in the carboxy-functionalized phenylmercury(II) complex are also presented here. Color changes are either associated with proton transfer or loss, or isomerization.<\/jats:p>","DOI":"10.1021\/acs.jpca.7b09490","type":"journal-article","created":{"date-parts":[[2017,11,10]],"date-time":"2017-11-10T13:05:53Z","timestamp":1510319153000},"page":"9243-9251","source":"Crossref","is-referenced-by-count":27,"title":["Seven Chromisms Associated with Dithizone"],"prefix":"10.1021","volume":"121","author":[{"given":"Lumanyano L.
