A novel photochromic dithienylmaleimide (TMF) appended with two ferrocene units was synthesized from 2,3-bis(5bromo-2-methylthiophen-3-yl)fumaronitrile. Its photochromic properties, electrochemical properties and magnetism were studied. Both fluorescence emission and redox potential were reversibly changed accompanying the open and closed-ring photoisomerization of TMF with UV/vis light irradiation and electrochemical redox. TMF may be used for fluorescent switch and electrochemical switch controlled by both light and electrochemical redox. (c) 2006 Elsevier Ltd. All rights reserved.

Two newphotochromic 1,2-bisthienylethenes containing triphenylamine were conveniently prepared; large cyclization quantum yields and obvious fluorescent changes regulated by the photoisomerization were observed. The substitution effect on the photochromic process is discussed based on these systems.
