Preparation, Spectral Properties, and Electron Affinity of Bis(thiadiazolo)quinoxaline and Bis(thiadiazolo)phenanthroquinoxaline as n-Type Semiconductors

摘要

Bis(thiadiazolo)phenanthroquinoxaline and bis(thiadiazolo)-quinoxaline derivatives were prepared as a new candidate of n-type semiconductors and their electronic properties were investigated by spectroscopic and electrochemical measurements. The bis(thiadiazolo)phenanthroquinoxaline having the trifluoromethyl groups indicates n-type characteristic in an organic field-effect transistor.
