Abstract


In recent years , the organic conjugated to the study of the synthesis and properties of functional molecules has attracted extensive attention from scientists . This dissertation organic conjugated functional molecules build this theme, through the regulation of intramolecular energy transfer and electron transfer process , carried out a series of studies in the field of chemical sensors , molecular self-assembly . This thesis is divided into four chapters , based on the design, synthesis and properties of organic functional molecule research , carried out the following aspects of the research , the first chapter , the organic functional molecules in chemical sensors , ultra- molecular chemical self-assembly Research progress described . Chapter , the design and synthesis of a new class of dual-channel absorption - fluorescence in response to copper ion chemical sensors . The sensor may be selectively complexing with copper ions , thereby causing molecular system within the ligand to the metal ions of the charge transfer ( LMCT) , accompanied by system significant change of the absorption spectrum of the color of the solution changed from colorless to blue , to achieve a convenient fast \The third chapter , the design, synthesis and characterization of several new joint ethylene alkynyl derivatives , and to explore the self-assembly conditions . Spiropyran itself steric hindrance is too large , it will affect the diyne π-π interaction , thus affecting the self-assembly process of the compounds 11, 13 and 26 ; try adjusting compound 18 with compound 19 assembly morphology by changing the conditions for self-assembly , self-assembly of the power of the study to explore ; initially explored the compound 25 with the one-dimensional self-assembled condition , and to provide a basis for the design of the new poly linked ethylene alkyne molecules assembled module structure . Chapter IV , designed and synthesized by a simple acid-base driven molecular shuttle . The initial UV test results show that the molecular axial end of the sulfur -sulfur bond with gold particles can interact , and bonding occurs . Meanwhile, on the sleeve to the molecular axis of the macrocyclic modification of the adsorption of the π-π occurs with nanotube pyrene . Which lay the foundation for the next step, we regulate gold nanoparticles adsorbed on carbon nanotubes detachment .
