Dipole moments and molecular structure of picrates of aromatic hydrocarbons and heterocyclic amines
, 1961 Dipole moment measurements have been made in the case of a few aromatic hydrocarbon picrates, the values obtained being 2·18, 2·25, 2·97 (all in Debye units) for picrates of naphthalene, acenaphthene and phenanthrene respectively and the results ...

A new bile acid-derived lariat-ether: Design, synthesis and cation binding properties [PDF]
, 2003 A new chola lariat ether (1, a 21-crown-6) was constructed from readily available precursors. The association constant of compound 1 with alkali metal picrates was measured using Cram’s extraction protocol.
