This makes them excellent candidates for organic linkers in the construction of photochromic coordination polymers. Such a photochromic two-dimensional coordination polymer has been prepared using <jats:italic>N<\/jats:italic>,<jats:italic>N<\/jats:italic>\u2032-bis(pyridin-4-ylmethyl)naphthalene-1,8:4,5-bis(dicarboximide) (DPMNI). In crystallization tubes, upon slow diffusion of an MeOH solution of cadmium perchlorate into a CHCl<jats:sub>3<\/jats:sub> solution of DPMNI, the complex poly[[bis[\u03bc<jats:sub>2<\/jats:sub>-2,7-bis(pyridin-4-ylmethyl)benzo[<jats:italic>imn<\/jats:italic>][3,8]phenanthroline-1,3,6,8(2<jats:italic>H<\/jats:italic>,7<jats:italic>H<\/jats:italic>)-tetrone-\u03ba<jats:sup>2<\/jats:sup>\n                  <jats:italic>N<\/jats:italic>:<jats:italic>N<\/jats:italic>\u2032]bis(perchlorato-\u03ba<jats:italic>O<\/jats:italic>)cadmium(II)] chloroform tetrasolvate], {[Cd(C<jats:sub>26<\/jats:sub>H<jats:sub>16<\/jats:sub>N<jats:sub>4<\/jats:sub>O<jats:sub>4<\/jats:sub>)<jats:sub>2<\/jats:sub>(ClO<jats:sub>4<\/jats:sub>)<jats:sub>2<\/jats:sub>]\u00b74CHCl<jats:sub>3<\/jats:sub>}<jats:sub>\n                     <jats:italic>n<\/jats:italic>\n                  <\/jats:sub>, (I), was obtained.
