Synthesis and characterization of a new class of liquid-crystalline, highly luminescent molecules containing a 2,4,6-triphenyl-1,3,5-triazine unit
摘要:
A new class of 2,4,6-triphenyl-1,3,5-triazine derivatives having long alkoxyl side chains have been synthesized by a Pd(0)/Cu(I)-catalyzed carbon-carbon coupling reaction. These compounds behave as liquid-crystalline materials and show quantum yields higher than 50% in photoluminescence. (C) 2001 Elsevier Science Ltd. All rights reserved.

of bis-(boron difluoride) complexes 1a–c derivedfrom substituted tetraketonates 2a–c are reported, and their mesomorphic and optical properties have been investigated. Two single crystals of mesogenic ligand 2a (n = 6) and nonmesogenic diboron complex 1a (n = 14) were obtained, and their single crystal and molecular structures were resolved. Results show that all 2a ligands (n = 6, 8, 10, 12, 14) formed
In the present work, four new cyanopyridone derivatives bearing terminal long chain alkyloxy substituents were designed and synthesized. All the synthesized target compounds were characterized by IR, NMR and Mass spectrometry. Further, their optical properties were examined in their solution state. The optical study showed that all the compounds can exhibit blue emissive behavior in their solution
