This study represents the first report on the chemical composition and antimicrobial activity of the essential oil from the branches of Jacaranda cuspidifolia Mart. Thirty-three compounds were identified by Gas Chromatography-Mass Spectrometry (GC-MS) and the major constituents of the essential oil were Palmitic acid (31.36%), (Z) − 9,17-Octadecadienal (12.06%), Ethyl palmitate (3.81%), Perhydrofarnesyl acetone (2.07%), γ-Maaliene (1.88%), and Cedro (1.42%) and 9,12-Octadecadienoic acid ethyl ester (1.42%). The in vitro antimicrobial activities of the essential oil were evaluated by the disc diffusion method, and the inhibition zones against Escherichia coli, Staphylococcus aureus and Candida albicans were 7.10, 8.20 and 7.25 mm, respectively. The oil showed moderate activities against E. coli, S. aureus and C. albicans with minimum inhibition concentration (MIC) values of 17.3 mg/mL, 12.9 mg/mL and 16.0 mg/mL, respectively.

To confirm how different anions influence sup-ramolecular self-assembly of lanthanide-organic frameworks (LnOFs) as well as their luminescent properties, a new flexible achiral tripodal ligand, 1,1,1-tris-{[(2'-benzylaminoformyl)phenoxyl]methyl}ethane (L) and the LnOFs {[EuL(NO(3))(3)]·1.5CHCl(3)}(n) and [EuL(pic)(3)](n) have been designed and assembled. In the two LnOFs, {[EuL(NO(3))(3)]·1.5CHCl(3)}(n) demonstrates an unprecedented chiral noninterpenetrated two-dimensional (2D) honeycomblike (6,3) (hcb, Schläfli symbol 6(3), vertex symbol 6·6·6) topological network, and [EuL(pic)(3)](n) confirms an unusual chiral LnOF with three-dimensional (3D) (10,3)-a (srs, SrSi(2), Schläfli symbol 10(3), vertex symbol 10(2)·10(4)·10(4)) topological framework. Also the anion-induced structures and energy transfer processes in the luminescence behavior of the two LnOFs were discussed in detail.
