ORGANIC PHOTOSENSITIVE DEVICES COMPRISING ARYL SQUARAINES AND METHODS OF MAKING THE SAME

摘要

There is disclosed squaraine compounds of formula (I): wherein each of Y1 and Y2 is independently chosen from an optionally substituted amino group and an optionally substituted aryl group. Also described are organic optoelectronic devices comprising a Donor-Acceptor heterojunction that is formed from one or more of the squaraine compounds. A method of making the disclosed device, which may include one or more sublimation step for depositing said squaraine compound, is also disclosed.
