Nitroaromatics as n-type organic semiconductors for field effect transistors

The nitro group (NO2) is one of the most common electron-withdrawing groups but it has rarely been used in the design of organic semiconductors (OSCs). Herein, we report the n-type semiconducting behavior of simple fluorenone derivatives functionalized with NO2and CN groups. While the electron mobilities measured in the thin film field-effect transistors are modest (10?6-10?4cm2V?1s?1), the nitrofluorenone OSCs offer excellent air-stability and remarkable tunability of energy levelsviafacile modification of the substitution pattern. We study the effect of substituents on the electrochemical properties, molecular and crystal structure, and the charge transport properties of nitrofluorenones to revitalize the underestimated potential of NO2functionalization in organic electronics.

SYNTHESIS OF POLYNITRO-SUBSTITUTED 2-CARBOXYBIPHENYLS

Methods were developed for the synthesis of polynitro-substituted 2-carboxybiphenyls.During the nitration of 2-carboxybiphenyl under rigorous conditions or during the heating of nitro-substituted 2-carboxybiphenyls in concentrated sulfuric acid or high-strength oleum decarboxylation and cyclization occur with the formation of nitro-substituted biphenyls and fluorenone.
