CC coupling of 1,7‐dibromoperylene bisimide with sterically hindered 2,6‐di‐ tert ‐butylphenol by a carbon nucleophilic substitution reaction in the absence of transition‐metal catalysts gave novel halochromic perylene bisimides (see picture). The corresponding phenolate ions of these compounds exhibit unprecedented NIR spectroscopic properties including strong absorption with maxima at around 1200 nm.
