The pressure effect on single crystals of photochromic furylfulgide, [2‐[1‐(2,5‐dimethyl‐3‐furyl)‐2‐methylpropylidene]‐3‐isopropylidenesuccinic anhydride], has been investigated up to about 5 GPa through the measurement of absorption spectra at room temperature. The absorption edge of the opened‐ring (E‐form) molecules in single crystal at about 2.6 eV shifts to lower energy with increasing pressure. The absorption band corresponding to the closed‐ring (C‐form) molecules is observed in the range of 2.0–2.6 eV and shows a red‐shift with increasing pressure. The photo‐induced reversible isomerization was observed under high pressures, as is the same as under the atmospheric pressure. Pressure‐induced transition to C‐form molecules was observed when the pressures were over 2.5 GPa.
