We describe the application of the LCST of a naphthalene-functionalised polyNIPAM derivative as a convenient, tuneable and reversible method to disrupt complex formation with CBPQT(4+) in water.

An efficient regioselective naphthoannulation strategy able to fuse a newly formed naphthalene ring at its 1,2- and 3,4- positions to two different heterocycles has been developed.

In the title compound, C(24)H(16)Cl(2)N(2)O(2)·2C(3)H(7)NO, the two C=O groups adopt an anti orientation. The two amide groups are twisted away from the naphthalene ring system by 59.10 (4) and 68.22 (4)°. The crystal packing is stabilized by N-H⋯O and C-H⋯O hydrogen bonds.

In the title compound, C(13)H(12)O, the cyclo-pentene ring fused with the naphthalene group adopts an envelope conformation. The cyclo-pentene torsion angle, with the fusion bond at the centre, has a magnitude of 1.16 (16)°. In the crystal, neigh-bouring mol-ecules are connected through O-H⋯O hydrogen bonds into an R(4) (4)(8) ring motif. The crystal packing also features weak π-π stacking inte...

background: polycyclic aromatic hydrocarbons (pahs) such as naphthalene (nap) are organic pollutants that have spread widely in littoral marine ecosystems. we aimed to study the effect of acute and prolonged exposure to naphthalene (nap) on plasma cortisol and thyroid levels in mature and immature liza klunzingeri mulet. methods: in acute stress experiment, the treatment group received 2μl g-1 ...

Estrogenicity was assessed using the Saccharomyces cerevisiae-based Lac-Z reporter assay and was reported as the logarithm of the inverse of the 50% molar beta-galactosidase activity (log[EC50(-1)]). In an effort to quantify the relationship between molecular structure of polycyclic aromatic hydrocarbons (PAHs) and estrogenic gene expression, a series of PAHs were evaluated. With noted exceptio...
