Eight novel, large‐ring chromogenic benzocrown compounds have been synthesized. Two incorporate 19‐and 20‐membered crown units with six ring oxygens. Six others contain large rings ranging from 21‐crown‐7 to 30‐crown‐10. For all six benzocrown compounds, the 4′‐(2″,4″‐dinitro‐6″‐trifluoromethylphenyl)amino group was employed as the chromogenic unit. In addition, 4′‐picrylamino and 4′‐(2″,6″‐dinitro‐4″‐trifluoromethylphenyl)amino groups were also attached to benzo‐21‐crown‐7.
