In the title compound, C16H15NO, there is a weak intra­molecular C-HO contact which leads to a planar acryl­amide moiety. The phenyl ring forms an angle of 8.30 (2)° with the mean plane of the acryl­amide moiety. The benzyl group is tilted against the cinnamamide unit, with the ring forming an angle of 77.11 (2)° with the cinnamamide unit mean plane. In the crystal, mol­ecules are linked via N-HO and C-HO hydrogen bonds and C-H inter­actions, forming chains propagating along [001]. The chains are linked via further C-H inter­actions, forming layers parallel to the ac plane.

The title compound, C9H9NO, crystallized with two independent mol­ecules (A and B) in the asymmetric unit. The conformation of the two mol­ecules differs slightly with the phenyl ring in mol­ecule A, forming a dihedral angle of 15.38 (12)° with the oxime group (O-N=C), compared to the corresponding angle of 26.29 (11)° in mol­ecule B. In the crystal, the A and B mol­ecules are linked head-to-head by O-HN hydrogen bonds, forming -A-B-A-B- zigzag chains along [010]. Within the chains and between neighbouring chains there are C-H inter­actions present, forming a three-dimensional structure.

The adsorption of three different dyes on similarly derived carbon materials from date palm leaves was studied. The adsorption kinetics and equilibrium data were investigated based on dyes adsorption tests. The break-through time was noted with a UV-VIS spectrometer to determine the maximum capacity of the date-palm leaf derived carbon material. The types of surface groups present on the carbon surface of the activated date palm leaf derived material were studied. Also, the adsorption will be carried out by dynamic process in a flow-through column and the dynamic adsorption capacity and breakthrough curve were determined.

9-Anthranylcarbaldehydes were converted to alkyl 9-anthranylacrylates and 9-phenacylethenylanthracenes. Alkyl 9-anthranylacrylates are brominated to alkyl 9-bromoanthran-10-ylacrylate. Suzuki-reactions with arylboronic lead to alkyl 9,10-arylanthranylacrylates. The alkyl 9-anthranylacrylates and 9-phenacylethenylanthracenes were subjected to cycloaddition reactions to give the respective cycloadducts.

In the title mol-ecule, C13H9NO, the fluorene system and the oxime group non-H atoms are essentially coplanar, with a maximum deviation from the fluorene mean plane of 0.079 (2) Å for the oxime O atom. A short intra-molecular C-H⋯O generates an S(6) ring. In the crystal, mol-ecules related by a twofold screw axis are connected by O-H⋯N hydrogen bonds, forming [100] chains Within these chains, mol-ecules related by a unit translation along [100] show π-π stacking inter-actions between their fluorene ring systems with an inter-planar distance of 3.347 (2) Å. The dihedral angle between the fluorene units of adjacent mol-ecules along the helix is 88.40 (2)°. There is a short C-H⋯π contact between the fluorene groups belonging to neighbouring chains.
