Isonicotinamide(INA) and p-Cyanobenzoic acid (CNBA) interact in alcohol solutions to give co-crystals INA-CNBA and INA(CNBA)2. These co-crystals have been characterized by single crystal X-ray crystallography and were further studied by infrared spec

The bis-p-chlorocinnamate of 10,12-docosadiyn-1,22-diol (Cl-Cin-22) interacts with 60Co γ radiation to give a polydiacetylene (PDA) soluble in organic solvents. This PDA has been previously studied with respect to its optical spectroscopy and excito

The polydiacetylene (PDA) from the bis-n-propylurethane of 5,7-dodecadiyne-1,12-diol (PUDO) undergoes a first order phase transition near 135°C that is associated with a color change from blue at temperatures below the transition to red at temperatu
