For most photochromic compounds, irradiation of the solution or solid results in a deepening of the color (positive photochromism). Less studied are those characterized by photoinduced bleaching (negative or

Besides simple molecular electrochromic switches, complex TTF-based MIMs with unique optical properties have been constructed. In 2012, rotaxane 18 with a structure similar to previously reported donor–acceptor rotaxanes was
