新型八元噻吩-乙炔-乙烯环状共轭低聚物的合成及其超分子行为
Synthesis and Supramolecular Performance of a New Type of Eight-membered Thiophene-acetylene-ethylene Cyclic Conj ugated Oligomer
摘要
Abstract
In recent years,Masahiko Iyoda reported a series of macrocyclic compounds composed of thiophene,acetylene,and ethylene building blocks.These macrocyclic compounds own unusualπconj ugated systems and inner cavity structure,which bring a-bout some unique photoelectric performances,such as the two-photon properties and nonlinear optical responses.Here we synthesized a new cyclo[8]thiophene-acetylene-ethylene compound by introducing bithiophene groups.As shown in the crystal structure,uncom-mon S-πweak interactions play key roles during the crystal growth of thiophene rings,intramolecular and intermolecular channel are formed as the result of molecular cavity and perfect crystal packing.Scanning electron microscope(SEM)data show that the macrocy-clic compound forms several centimeters long acicular fiber cluster by self-assembling.Furthermore,fluorescence emission spectrum shows that fluorescence intensities of macrocyclic compound dramatically quench with an increase of the fullerene (C60 ),which con-firms the supramolecular and electronic transfer performance between the electron donor of the macrocyclic compound and the elec-tron acceptor of the fullerene molecule.关键词
