Band electronic structure of polyphenanthrene and polyacene dopes with lithium

Article Abstract:

The band electronic structures of polyphenanthrene (PPh) and polyacene (PA) doped with lithium were calculated and analyzed applying the extended Huckel level theory. It can be concluded that the deep occupied levels that arise from PA-type edge structure could be responsible for the irreversible capacity loss observed during the charging-discharging process in PAs and polycyclic aromatic hydrocarbons (PAHs) materials.

Spectroscopic investigations of ADMA encapsulated in pyrogallol[4]arene nanocapsules

Article Abstract:

The investigation of inner phase properties of the pyrogallol[4]arenes hexamer by using the solvent-dependent properties of 1-(9-anthryl)-3-(4-dimethylaniline) propane (ADMA) indicated the majority of ADMA to be sequestered in an extended conformation with the crystallization solvent.

Maristentorin, a novel pigment from the positively phototactic marine ciliate Maristentor dinoferus, is structurally related to hypericin and stentorin

Article Abstract:

The photoreceptor pigment of the heterotrich ciliate, Maristentor dinoferus is characterized. It is structurally similar to those of Stentor coeruleus and Blepharisma japonicum but differs significantly in that it bears no aromatic hydrogen.
