چکیده

In the title compound, C(12)H(10)N(2)O(3), the five- and six-membered rings form a dihedral angle of 83.96 (6)°. The nitro group is twisted by 5.92 (8)° from the plane of the attached benzene ring. In the crystal, weak inter-molecular C-H⋯O hydrogen bonds link the mol-ecules into columns in the [100] direction, with a short distance of 3.725 (3) Å between the centroids of benzene rings inside these columns.

Conformationally switchable non-cyclic tetrapyrrole receptors: synthesis of tetrakis(1H-pyrrole-2-carbaldehyde) derivatives and their anion binding properties.

A series of tetrakis(1H-pyrrole-2-carbaldehyde) receptors (2, 4, and 6) were synthesized in two steps from commercially available starting materials. The anion binding properties of these receptors can be tuned through electronic switching to stabilize a conformation displaying high affinity for the dihydrogenphosphate and pyrophosphate anions (as the tetrabutylammonium salts) in chloroform.
