A facile way to achieve all-photonic logic functions and photo-printing based on a donor–acceptor Stenhouse adduct.

Herein, a simple bi-photochromic molecule containing a donor–acceptor Stenhouse adduct and azobenzene moiety was synthesized. It can achieve all-photonic multimolecular logic functions and photo-printing. This molecule could provide a novel platform for exploring multifunctional molecular logic devices.
