In this contribution pyrazole is identified as an excellent anchor group that forms high quality films under pH controlled conditions, allowing the modulation of electrical properties with a more efficient electronic coupling in basic conditions.

1 Introduction pH control is the process of adding acid or base to opposing solutions aiming to achieve a solution of pH 7, defined as neutral solution. The function of the controller is to achieve a neutral output of the system. This in itself is not an easy problem to solve as pH control of a neutralisation process is a difficult non-linear control problem. This is largely due to the inherent...
