could be generated in gram quantities with relatively high overall yields. Three organic
semiconductors containing thieno [3, 2-b] pyrrole were synthesized in good yields without
requiring time-consuming column purifications. The synthesis, optical and electrochemical
properties were systematically investigated. 1 Introduction 2 Experimental 3 Synthesis and
