A first example of 1D coordination polymer [MnTHPP·H2O·(DMF)2 (1)] with right-handed helicity and opticity was successfully assembled. Crystal analyses indicate that the right-handed helical assembly is based on coordination bonds from peripheral to center, associating with the saddle distortion of the molecular planes. In its crystal architecture, MnTHPP [manganese (III) ion coordinated by 5,10,15,20-tetra(4-hydroxyphenyl) porphyrin] molecules were ligated each other via the axial coordination between –PhO− → MnIII (peripheral to center model, from the peripherally deprotonated hydroxyphenyl to the central metal of the neighbor molecule) to construct the right-handed helices, and the helices are sustained by plentiful hydrogen bonding. Meanwhile DMF molecules are entrapped within the voids among the helices. This is a rare example of the multiporphyrin arrays with right-handed helices bearing opticity.
