Opioid Analgesics: Chemistry and Receptors

The swiftly burgeoning study of the prior 20 years on agonist-antagonist analgesics and opioid receptors makes this exhaustive overview of opioid anal­ gesics fairly correct and well timed. After an introductory bankruptcy the extra 12 chapters start logically with morphine and congeners (4- epoxymorphinans) and finish with opioid receptors.

Using their numerical model, Koster et al. were also able Polymer Solar Cells 29 to describe accurately the light intensity dependence of both the open circuit voltage and the short circuit photocurrent for polymer–fullerene solar cells [155, 156]. In contrast, Schilinsky et al. and Waldauf et al. used an extended numerical description according to the p–n junction model and demonstrated as well a proper description of light intensity-dependent device current–voltage characteristics [127, 157, 158].

The energetic order of |A+ D– r = ∞ and |A ∗ D r = ∞ may be reversed for PFB:F8BT vs TFB:F8BT. The inset shows the band offsets at a type II heterojunction. 2 nm). Hence, TFB:F8BT blends lead to efficient light-emitting devices whereas polaron pair dissociation is largely increased for PFB:F8BT blends, as required for solar cells. 4 Organic–Inorganic Hybrid Polymer Solar Cells Greenham et al. studied the first hybrid systems containing CdS or CdSe nanoparticles embedded in MEH-PPV [249]. As an aggregation-preventing ligand for the nanoparticles, the surfactant trioctylphosphine oxide (TOPO) was used.

A 10 µm × 10 µm and b 500 nm × 500 nm, which was taken in the vicinity of the sample marked by the white square in (a). (Reprinted with permission from [236], © 2004, American Chemical Society) Polymer Solar Cells 49 obtained for F8BT-enriched blends (PFB:F8BT 1 : 5). They attributed this discrepancy between the photoluminescence quenching and EQE to charge transport limitation rather than to charge generation. The authors also developed a simple model describing the interfacial area between F8BT- and PFB-rich domains and found a linear trend with respect to the EQE [237].
