Incorporating electron donor functionalities into porous coordination frameworks enables the strong binding of electron-withdrawing guests, but such binding typically occurs irreversibly. Here, a structurally dynamic 2D coordination network incorpora

A simple yet effective method for the formation of thiophene-fused π-systems is reported. When arylethynyl-substituted polycyclic arenes were heated in DMF in the presence of elemental sulfur, the corresponding thiophene-fused polycyclic arenes were
