  The host compounds 9-(4-methoxyphenyl)-9H-xanthen-9-ol (H1) and 9-(3-methoxyphenyl)-9H-xanthen-9-ol (H2) form inclusion compounds with morpholine (MORPH). The H1·½MORPH structure crystallised in the monoclinic space group P21/c with Z = 4. The unit cell dimensions were determined as: a = 8.9358(6) Å, b = 15.0970(10) Å, c = 13.1591(9) Å, β = 101.253(2)° and V = 1741.1(2) Å3. The final R indices obtained for this structure was [I > 2σ (I)] R1 = 0.0389 (wR2 = 0.1040). 2H2·2MORPH was solved successfully in P-1 with Z = 2, unit cell dimensions: a = 8.9784(18) Å, b = 12.595(3) Å, c = 18.932(4) Å, α = 77.78(3)º, β = 88.78(3)°, γ = 72.22(3)° and V = 1990.3(9) Å3. For this structure R1 = 0.0438, wR2 = 0.1072 for [I > 2σ (I)]. The compounds obtained from grinding experiments were analysed using powder X-ray diffraction.

• Quenching behavior of singlet excited 9-arylxanthylium cations
  作者：Maria R. Valentino、Mary K. Boyd

  日期：1993.10

  Several 9-arylxanthylium tetrafluoroborate salts (Ar = H, p,m-F, p,m-Me, m-OMe) were synthesized by reaction of the corresponding 9-arylxanthen-9-ol with fluoroboric acid. Spectral characteristics of the xanthyl cations were identical to those previously reported for the cations generated by alternate methods. The 9-arylxanthyl cation fluorescence was quenched by the addition of H2O, MeOH, i-PrOH, and t-BuOH. Stern-Volmer analysis of the fluorescence quenching gave bimolecular excited-state rate constants ranging from 10(6) to 10(10) M-1 s-1, with the larger rate constants associated with electron-donating substituents. Hammett plots of log[k(q)(X)/k(q)(H)] versus sigma(hnu) gave negative p values for each quencher, opposite to the substituent dependence observed for ground-state cations reacting with nucleophiles. The relative quenching order also differs from the order observed for ground-state cation reactions. The mechanism for quenching of the singlet excited 9-arylxanthylium cations is evaluated in terms of nucleophilic attack. The possibility of an electron-transfer mechanism is considered and eliminated.
