Abstract
A novel perylene diimide (PDI) derivative with typical amphiphilic character, 2, was designed and prepared. The spectroscopic studies on this compound in solution revealed the face-to-face dimeric configuration and effective π - π interaction between the two perylene rings. This amphiphilic PDI derivative was fabricated into highly ordered films by Langmuir - Blodgett (LB) technique and fabricated into an organic field effect transistor (OFET), which shows carrier mobility around 0.05 cm2 V-1 s-1 and current modulation of 103. This OFET performance is much better than that of monomeric PDI 1 and can be attributed to the unique face-to-face structure of 2, which promotes the interactions between neighboring PDI ring in LB film as indicated by the π - A isotherms and UV - vis absorption.
