The electron-donating strengths of donor (D) moieties in thirteen donor-pi-acceptor systems (D1-pi-A to D13-pi-A wherein -pi- and A represent butadiene and cyanoacrylic acid units, respectively) have been studied using ...

Isosmaragdyrin with an N3C2 core is successfully achieved by introducing a 2,6-di-m-phenylpyridine unit. The core is utilized to stabilize the Rh(I) ion in the N–Rh(I)–N bonding mode and the Pt(II) ion in the (N^C)N fashion ...

Supramolecular self-assembly and molecular recognition processes are driven mainly by positive cooperativity in noncovalent interactions. Here, we report a large variety of hydrogen-, tetrel-, chalcogen-, pnicogen-, halogen-, ...
