Glass-forming Photoconductive Organic Compounds II1: Glass-forming Properties of 1,3,5-Triaryl-2-pyrazolines

Abstract Glass-forming properties of 2-pyrazoline derivatives were examined and discussed in terms of the molecular structure. The results show that the molecular shape of 1,3,5-triaryl-2-pyrazolines is responsible for the glass-forming properties of these compounds. Glass transition points of several 1,3,5-triaryl-2-pyrazoline derivatives were measured.
