An Unusual Independent 1D Metal−Organic Nanotube with Mesohelical Structure and 1D → 2D Interdigitation

A novel one-dimensional (1D) metal−organic nanotube {[Cd2(ADC)2(bpp)3(H2O)]2·8H2O}n (MONT-1), based on mixed organic ligands, has been synthesized and characterized. MONT-1 presents the first independent 1D metal−organic nanotube with mesohelical structure and a fascinating topology of 1D → 2D interdigital architecture with side arms. This compound also exhibits high thermal stability and blue-shift emission with large intensity enhancement compared with that of the free ligand and can be explored for potential blue luminescent materials.
