Various 2,5-diarylarsoles showed unexpected mechanochromic properties
Alongside inspiring puns for infantile chemistry journalists, scientists in Japan have experimentally demonstrated that a class of heteroles known as arsoles can change colour under pressure.
Theorists predicted that these arsenic-containing compounds could form interesting optical and electronic materials, based on their low aromaticity and the high barrier to structural inversion. However, the bottom line in arsole synthesis is that volatile toxic arsenic intermediates have always limited their investigation…
