Abstract

The inclusion compounds of 14-hydroxy-14-toluenyldibenzo[a:j]xanthene (H) with the guests acetone (H·ACE), pyridine (H·PYR) and N,N-dimethylformamide (H·DMF) were all successfully solved in the triclinic spacegroup P-1 with unit cell dimensions for H·ACE: a = 9.415(2) Å, b = 9.730(2) Å, c = 12.994(3) Å, α = 82.65(3), β = 76.69(3), γ = 88.67(3), Z = 2; for H·PYR: a = 9.482(2) Å, b = 10.169(2) Å, c = 13.089(3) Å, α = 106.59(3), β = 95.91(3), γ = 90.35(3), Z = 2 and for H·DMF: a = 9.537(19) Å, b = 10.055(2) Å, c = 13.129(3) Å, α = 79.18(3), β = 74.42(3), γ = 86.46(3), Z = 2. The thermal stabilities for all compounds were investigated and in particular the kinetics of desolvation for the DMF compound was determined using both isothermal and non-isothermal methods.

Index Abstract

The host compound 14-hydroxy-14-toluenyldibenzo[a:j]xanthene forms inclusion compounds with the guests acetone, pyridine and N,N-dimethylformamide. The crystal structures were determined and their thermal stabilities investigated. The kinetics of desolvation for the DMF compound was determined using both isothermal and non-isothermal methods.
