Advanced Functional Materials, EarlyView.Self‐assembled monolayers (SAMs) are promising hole‐transporting materials for organic photovoltaics (OPVs), but suffer from self‐aggregation and poor large‐area uniformity. We find that interfacial modification using nicotinic hydrazide can eliminate the residual SAM aggregates by forming energetically favorable complexes, yielding uniform SAM.

, 1999 The basic theory behind NMR spectroscopy is described. The various NMR parameters that can be obtained from NMR spectra are explained, including the chemical shift, spin-spin coupling, and relaxation. Some explanation of the theory of how NMR is detected is also presented. © 1999 Elsevier Ltd All rights reserved.
