Fluorinated 1,8-naphthalimides: Synthesis, solid structure and properties

Three fluorinated 1,8-napthalimides were synthesized from acenaphthene. Their structures were characterized by NMR and EI-MS analyses. The structures of compounds 1b and 1c were also confirmed by X-ray diffraction analysis, which showed that they possessed different packing models. Their optoelectronic properties were investigated. The results indicated that all of the naphthalimides possess good solubility and low LUMO energy level, which make them good solution processing candidates in n-type semiconductor.

Novel dyes based on naphthalimide moiety as electron acceptor for efficient dye-sensitized solar cells

Four novel naphthalimide-based dyes (D-1, D-2, D-3 and D-4) were synthesized and utilized as sensitizers in dye-sensitized solar cells (DSCs), in which the triphenylamine (TPA) or indoline groups, naphthalimide unit and carboxylic group were functionalized as electron donor, acceptor and anchoring group, respectively. The naphthalimide unit was employed as the π-conjugation ring and electron acceptor for effectively realizing intramolecular charge separation in the oxidized states. In the series of dyes, the LUMO orbital is delocalized mainly on naphthalimide moieties, especially on the carbonyl group. Consequently, the LUMO electrons are isolated from the carboxyl anchoring group (-CH2CO2H) due to the presence of the methylene group, which could suppress the electron injection efficiency from the excited dyes to the TiO2 conduction band, thus leading to the inferior efficiencies of 1.10, 1.18, 2.27 and 2.70%, respectively, even though they exhibit broad spectral response and high extinction coefficients.

Sterically fixed dithiolate ligands and their zinc complexes: Derivatives of 1,8-dimercaptonaphthalene

The synthesis of two new dithiols, 1,8-dimercapto-2,7-di(tert-butyl)naphthalene (H2L1) and 1,8-dimercaptonaphthoic anhydride (H2L2), is described. They react with diethylzinc to yield the polymeric complexes L1Zn and L2Zn. L1Zn dissolves in the presence of pyridine to form [L1Zn·py]x, which is presumed to be dimeric. Both L1Zn and L2Zn react with neocuproin. Structure determinations have confirmed the tetrahedral ZnN2S2 coordination in the resulting LZn·neo complexes.

Nuclear spin-spin coupling via nonbonded interactions. 8. The distance dependence of through-space fluorine-Fluorine coupling

The 19F19F nuclear spin-spin coupling constants J(FF) for a set of eighteen compounds related structurally to 1,8-difluoronaphthalene were measured by 19F NMR spectroscopy. The FF distances d(FF) in these compounds were determined by ab initio 3-21G* molecular orbital calculations. Consistent with the lone-pair overlap theory of the origins of through-space 19F19F coupling, an exponential relationship is found between J(FF) and d(FF) (regression coefficient r2 = 0.991), and a linear relationship is found between J(FF) and the extent of the overlap interaction between the in- plane fluorine 2p lone-pair orbitals (regression coefficient r2 = 0.993). The magnitudes of these lone-pair interactions were estimated from molecular orbital energies obtained by ab initio 6-31G* calculations for a model consisting of a pair of HF molecules separated by various distances.
