摘要 New hexaalkoxydibenzo[a,c]phenazines (HDBPs) with six-carbon long chains have been prepared, and their mesogenic behavior investigated. The incorporation of six peripheral alkoxy groups onto the larger, dipolar core bearing nitrogen atoms showed interesting thermal properties. The crystal-to-mesophase transitions for the HDBPs (K–col) are similar to the triphenylenes, but the clearing temperatures (Col–I) are shifted upwards by approx. 60 °C. HDBP therefore possesses stable hexagonal mesophases in a fairly broad temperature range and form homeotropically aligned films.
