COMPLEXATION WITH DIOL HOST COMPOUNDS .8. STRUCTURES AND THERMAL-ANALYSIS OF 1,1,6,6-TETRAPHENYLHEXA-2,4-DIYNE-1,6-DIOL WITH SELECTED KETONES

The structures of three inclusion compounds of 1,1,6,6-tetraphenylhexa-2,4-diyne-1,6-diol with methyl ethyl ketone (1), diethyl ketone (2) and acetophenone (3) have been determined and their thermal decomposition investigated by thermogravimetry and differential scanning calorimetry.
