title: Cyclotetraazocarbazole--a multichromic molecule.
abstract: A macrocyclic cyclotetraazocarbazole was prepared. Surprisingly, during the investigation of its photochromic behavior a drastic color change from yellow to green upon irradiation in chlorinated solvents was observed, which was temperature dependent and could also be induced by acid/base addition. With these three inputs an integrated molecular logic gate including an OR, a NOT and an AND function was build.
