  A simple and efficient method has been developed for the synthesis of phenolic ethers using room-temperature ionic liquid, not only as solvent but also as promoter. Ionic liquid was recycled and subsequently reused without any loss of the product.
• From para-dimethoxybenzene toward crown benzenophanes: 1,3,10,14-tetraoxa[3.5]paracyclophane

  The title compound tetraoxa[3.5]paracyclophane (6) has been prepared and studied in order to investigate the evolution of spectroscopic properties in going from the monomer unit p-dimethoxybenzene (9) via the noncyclic bichromophoric reference compound 3b to 6. The X-ray structural analysis of 6 shows that the distance between the two aromatic carbon atoms linked to the smaller bridge is shorter than the van der Waals distance. The resulting electronic interaction is reflected by the perturbation of the UV spectrum of 6 (in particular by a distinct hypochromic effect) and in its charge-transfer complexes with TCNE and TCNQ, as compared to 9 and 3b. The fluorescence quantum yields show significant quenching as compared to 9. This process is related to the formation of a new, structureless red-shifted band with a maximum at 26 670 cm-1, comparable to that of the excimer of 9. From a Stern-Volmer plot the self-quenching rate constant of the latter, k(q) almost-equal-to 1.2 x 10(9) mol-1 s-1 is derived.
