噻吩乙烯类化合物的合成、聚集诱导发光和力致变色性能
Synthesis,Aggregation Induced Luminescence and Piezochromic Properties of Thiophene Ethylene Derivatives
摘要
Abstract
Most luminescent materials are greatly limited in their applications due to strong fluorescence quenching in solid state or high doping concentration.Therefore,it is particularly important to research and develop new materi-als that can exhibit excellent luminescent properties in aggregated states.Four compounds based on the thiophene ethylene skeleton structure,Br-thph,Br-2thph,Thph-czm,and 2Thph-czm were synthesized in this paper.The photophysical properties of this type of compound have been studied in detail in low concentration solutions,aggre-gates,and solid films.The results showed that all four compounds exhibited significant aggregation induced lumines-cence properties,with weak luminescence in low concentration solutions,but exhibited strong luminescence with in-creasing concentration or in aggregated states.Among them,compounds Br-thph and Br-2thph exhibit 410 and 180 times enhanced luminescence compared to low concentration solutions,while Thph-czm and 2Thh-czm exhibit 78 and 40 times enhanced luminescence,respectively.Moreover,all four compounds exhibited significant mechanoflu-orochromic effects and exhibited a certain spectral blue shift.Through preliminary exploration of the photophysical properties of these compounds,it is indicated that these novel thiophene ethylene derivatives have potential applica-tion value in anti-counterfeiting and display fields.关键词
