Deuterium-Induced Phase Transition of Crystalline Tolane-d10

Yasuhisa YAMAMURA, Kazuya SAITO, Haruo MATSUYAMA and Isao IKEMOTO

A deuterium-induced phase transition has been discovered in a molecular crystal of tolane-d10 by powder X-ray diffraction and differential scanning calorimetry experiments. The phase transition is of first-order. DSC measurements on solid binary solutions of tolane-h10 and tolane-d10 have shown that there is a critical point on the temperature-composition phase diagram of this binary system.
