Abstract

The results of growth from solutions of organic crystals of a new π-conjugated linear oligomer (Hex-O-Ph)₂-BTD consisting of benzothiadiazole (BTD), phenyl (Ph) and oxazole (O) units and n-hexyl terminal substituents are presented. Well soluble at 20°C in n-hexane (1.7 g/L) and acetone (1.9 g/L), (Hex-O-Ph)₂-BTD crystals are formed in the shape of films or plates up to 8 mm long and about 10 μm thick at the liquid–air interface within five days. The polymorphism and melting parameters of the new compound are determined by the method of differential scanning calorimetry. The structure of the single-crystal film is analyzed by Х-ray diffraction. The crystal structure of (Hex-O-Ph)₂-BTD is found to be formed from close-packed (001) layers with a thickness of d₀₀₁ = 2.39 nm.
