Abstract

A procedure has been developed for TAPC-type hole transport small molecules whose salient feature is the addition of an orthoester to the reaction medium. The product can be isolated in higher yield, in a purer state and in a shorter reaction time, all the while at a lower reaction temperature. Results indicate that the extensive and costly purification protocols usually required to attain electronic grade purity levels for these types of materials may not be necessary.
