Organic photosensitive devices comprising aryl squaraines and methods of making the same
There is disclosed squaraine compounds of formula I: wherein each of Y 1 and Y 2 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.
