Abstract:
We employed nanobeam X-ray diffraction using an X-ray spot size of 150 nm to investigate the local structure of P3HT thin films. We derived nanoscale real space maps of the X-ray diffraction properties at the π-π (020) diffraction peak. The X-ray data reveal a complex nanoscale structure of the polymer network with strong local variation where some areas of the film display a rather high degree of angular order. We quantify both the magnitude and direction of the angular order. Our results provide new insights into the local structural properties and connectivity of P3HT films.

π Molecular Orbitals of 1,3-Butadiene
The simplest conjugated diene is 1,3-butadiene: a four-carbon system where each carbon is sp2-hybridized and has an unhybridized p orbital that contains an unpaired electron. According to molecular orbital theory, atomic orbitals combine to form molecular orbitals such that the number...

Radicals: Electronic Structure and Geometry
Accordingly, the structure of a trivalent radical lies between the geometries of carbocations and carbanions. An sp2-hybridized carbocation is trigonal planar, while an sp3-hybridized carbanion is trigonal pyramidal. Here, the difference in geometry is...
