When developing chemical systems it’s of course important to gain a deep understanding of the chemical reaction process. Electric Literature of 4254-15-3,
New discogens based on the octasubstituted phthalocyanines (Pc) were synthesized: 2,3,9,10,16,17,23,24-octakis-phthalocyanine (1a), 2,3,9,10,16,17,23,24-octakis<4-(dodecylthio)-2-oxa-butyl>-phthalocyanine (1b), 2,3,9,10,16,17,23,24-octakis-phthalocyanine (1c), phthalocyanine 2,3,9,10,16,17,23,24-octa-n-dodecanoate (1d), S-(+)-2,3,9,10,16,17,23,24-octakis<4-(dodecyloxy)-2-oxa-pentyl>-phthalocyanine (1e), as well as their corresponding copper complexes (CuPc) 2a, 2b, 2c and 2e.They were characterized by microanalysis, IR, 1H and 13C NMR spectroscopies, and their mesomorphic behaviors were examined with DSC and optical microscopic methods.The products exhibited the following optical textures and transition temperature ranges: focal conic (1a, 95-267 grad; 2a, 108-304 grad), linear default (1b, 52-247 grad; 2b, 70-255 grad; 1c, 75-269 grad; 2c, 78-310 grad), fan-shaped (1d, 58-303 grad; 2e, 29-191 grad).Chiral discogenic PcH2 1e, however, showed a cholesteric-like texture (23-151 deg C) in which the transition of a platelet (blue phase) to a fan-shaped texture was observed.
