Self-aggregating calix[4]arenes carrying four DOTA ligands on the upper rim for stable complexation of paramagnetic GdIII-ions have already been proposed as MRI probes. In this work, we investigate the luminescence properties of TbIII-DOTA-calix[4]arene-4OPr containing four propyl-groups and compare them with those of the analog substituted with a phthalimide chromophore (TbIII-DOTA-calix[4]are...

The mol-ecule of the title compound [systematic name: 2-(4-tert-butyl-benz-yl)isoindoline-1,3-dione], C(19)H(19)NO(2), is V-shaped with a dihedral angle of 74.15 (7)° between the mean planes of the phthalimide unit and the benzene ring. The methyl groups of the tert-butyl substituent are disordered over two sets of positions, with an occupancy ratio of 0.700 (4):0.300 (4). In the crystal, inter...

As a result of the direct synthesis through oxidative dissolution of metallic copper powder in the presence of phthalimide and sodium hydride a new polymeric bimetallic coordination compound [Cu(phthal)4Na2(PrOH)2H2O]n was synthesized and characterized by a single crystal X-ray crystallography and IR spectroscopy. The copper(II) ions have a distorted tetrahedral environment (CuN4), while the co...

There is considerable current interest in developing methods to integrate nanoparticles into optical, electronic, and biological systems due to their unique size-dependent properties and controllable shape. We report herein a versatile new approach for covalent immobilization of nanoparticles onto substrates modified with photoactive, phthalimide-functional, self-assembled monolayers. Upon illu...

The title mol-ecule, C(11)H(11)NO(3), lies on a crystallographic mirror plane which bis-ects the plane of the phthalimide unit and contains the C and O atoms of the 2-methoxy-ethyl group.

In the title compound, C(14)H(6)F(3)NO(2), the benzene ring and the phthalimide ring system make a dihedral angle of 60.12 (7)°. Weak inter-molecular C-H⋯O and C-H⋯F hydrogen bonds are present in the crystal structure.

In the title compound, C(14)H(10)N(2)O(2), the phtalimide and 2-pyridylmethyl units are almost perpendicular, with an inter-planar angle of 85.74 (2)°. In the crystal, mol-ecules are linked by weak C-H⋯O inter-actions, forming chains running along the b axis. The packing is further stabilized by offset π-π inter-actions between adjacent pyridine rings, with a centroid-centroid distance of 3.855...

The phthalimide anion reacts by the SRN1 mechanism under photostimulation with different substrates. Whilst with 1-iodonaphthalene only reduction of the naphthyl radical is observed, with 1-iodoadamantane coupling at the carbon instead of at the nitrogen takes place. Introduction The mechanism of Radical Nucleophilic Substitution (SRN1) is a chain process with radicals and radical anions as int...
