2,5-Diphenylpenta-2,4-dienenitrile

Abstract

In the title compound, C17H13N, the dihedral angle between the two phenyl rings is 17.6 (1)°. An inter­molecular C—H⋯N hydrogen bond is found in the crystal structure, also a C—H⋯π inter­action involving the phenyl ring at position 5.

Multi-Component Synthesis of a Buta-1,3-diene-Linked Covalent Organic Framework

“…Molecular analog 1 is almost coplanar with a slight torsion angle of 15.09°between one benzene ring and the buta-1,3diene (SI, Figure S4, Table S1). 15 The near-planar structure of buta-1,3-diene promotes the formation of stacked 2D layered COFs. 16 Subsequently, we synthesized the COF by condensation of PTTA with acetaldehyde and PDA in one pot (Figure 1b, SI, Figure S5).…”
