Structure of a piperidine-modified calix[4]arene derivative and spectral resolution of its interaction with rare earth metals with chemometric methods.
A piperidine-modified calix[4]arene derivative was synthesized and its structure was confirmed with X-ray diffraction data. UV-visible spectroscopy was used to study its molecular recognition of rare earth ions. The results revealed the calix[4]arene derivative could separate tight metal picrate ion pairs by complexation with the rare earth metal ions in tetrahydrofuran. Resolution of the UV-visible spectra with chemometric methods revealed that the derivative and the rare earth ions Eu(3+), Dy(3+), and Tb(3+) formed ML(2) complexes with stability constants of 10(8.26), 10(8.29), and 10(7.41) respectively.

Phenylpropanoids and tetrahydrofuran lignans from Piper solmsianum.
A tetrahydrofuran lignan as well as the known tetrahydrofuran lignan, (-)-grandisin, and five phenylpropanoid derivatives were isolated from Piper solmsianum. Their structures were determined by means of spectral analyses, including 2D NMR techniques such as NOE-DIFF and HMBC 3J(C-H).
