Efficient Intermolecular Charge Transport in Self-Assembled Fibers of Mono- and Bithiophene Bisurea Compounds

Angew Chem Int Ed Engl. 1999 May 17;38(10):1393-1397. doi: 10.1002/(SICI)1521-3773(19990517)38:10<1393::AID-ANIE1393>3.0.CO;2-H.

Abstract

Hydrogen bonds between urea units allow self-organization of π systems in mono- and bithiophenes into fibers as shown schematically. In these fibers there is a surprisingly high mobility of charge carriers as determined by pulse-radiolysis time-resolved microwave conductivity measurements.
