Conjugated Inorganic–Organic Hybrid Polymers with p‐Block Elements

open access: yesAngewandte Chemie International Edition, Volume 65, Issue 2, 9 January 2026.
The influence of various p‐block element motifs on the photophysical properties of conjugated inorganic‐organic hybrid polymers is surveyed regarding applications in organic electronics. Recent advances in the use of heavier elements as well as heavier multiple bonds and the development of diverse (post‐)functionalization strategies suggest ample scope

Polyradical character and spin frustration in fullerene molecules: An ab initio non-collinear Hartree--Fock study

open access: yes, 2014
Most {\em ab initio} calculations on fullerene molecules have been carried out based on the paradigm of the H\"uckel model. This is consistent with the restricted nature of the independent-particle model underlying such calculations, even in single ...

The crystal and molecular structure of 2,7-di-tert-butyl-4,5,9,10-tetraphenylbenzo[1,2,:4,5]dicyclobutadiene: an exceptionally long C–C aromatic bond [PDF]

open access: yes, 1999
The X-ray determined structure of the title compound is reported; it was found that the annelated bonds are the longest observed in a benzene derivative [1.540(5) Å]; ab initio calculations (at the B3LYP/6-31G* and MP2/6-31G* levels of theory) were used ...

Quantum entanglement between electronic and vibrational degrees of freedom in molecules

open access: yes, 2011
We consider the quantum entanglement of the electronic and vibrational degrees of freedom in molecules with a tendency towards double welled potentials using model coupled harmonic diabatic potential-energy surfaces.

QSPR analiza polarografskih poluvalnih redukcijskih potencijala benzenoidnih ugljikovodika [PDF]

open access: yes, 2006
Correlation between the polarographic half-wave reduction potentials and the set of molecular descriptors of lower benzenoid hydrocarbons was made by the CROMRsel modeling procedure. The following descriptors were used in the modeling procedure: electron

'I Heard Beauty Dying': The Cultural Critique of Plastic in Gravity's Rainbow

open access: yes, 2007
This essay attempts to get a grasp on Pynchon's 700-plus page omnibus, Gravity's Rainbow, by focusing on the development of a single motif in the novel: plastic. It argues that Pynchon takes 1960s and 1970s critiques of supply-driven consumer capitalism,

Motion as manipulation: Implementation of motion and force analogies by event-file binding and action planning\ud [PDF]

open access: yes, 2011
Tool improvisation analogies are a special case of motion and force analogies that appear to be implemented pre-conceptually, in many species, by event-file binding and action planning.
