D-A type dicyanoethylenes modified by carbazole: Obvious aggregation-induced emission enhancement and high-contrast mechanofluorochromism
Two novel luminophores, namely CDCEEC-1 and CDCEEC-2, were synthesized from dicyanoethylene segments and D-A-type carbazoles. Decoration of dicyanoethylene with carbazole causes them to exhibit significant aggregation-induced emission enhancement (AIEE) behavior. Hence, while CDCEEC-1 and CDCEEC-2 e...

520 | |a Two novel luminophores, namely CDCEEC-1 and CDCEEC-2, were synthesized from dicyanoethylene segments and D-A-type carbazoles. Decoration of dicyanoethylene with carbazole causes them to exhibit significant aggregation-induced emission enhancement (AIEE) behavior. Hence, while CDCEEC-1 and CDCEEC-2 exhibit extremely weak luminescence in common solvents, they show intense emissions because they possess highly twisted molecular structures once the molecules aggregate as nanoparticles or as solid powders. As a result of their intramolecular charge transfer (ICT) behavior, both luminophores exhibit a bathochromic effect. The combination of ICT and AIEE features not only enables CDCEEC-1 and CDCEEC-2 to have intense solid-state yellow and orange-yellow fluorescent emissions with quantum efficiencies of 0.363 and 0.328, respectively, but also imparts them with reversible and high-contrast mechanofluorochromic (MFC) behavior as a result of phase transition between crystalline and amorphous states. This behavior resulted in the emission peaks shifting from 550 nm (yellow) to 621 nm (orange-red), and from 574 nm (orange-yellow) to 648 nm (red), respectively. Our research has shown that it is feasible to produce high-efficiency ICT-AIEE-MFC luminogens with tunable emissions by using a suitable combination and modulation of donors and/or acceptors. This provides novel insights into the use of these luminogens in optical applications. | ||

This behavior resulted in the emission peaks shifting from 550 nm (yellow) to 621 nm (orange-red), and from 574 nm (orange-yellow) to 648 nm (red), respectively. Our research has shown that it is feasible to produce high-efficiency ICT-AIEE-MFC luminogens with tunable emissions by using a suitable combination and modulation of donors and/or acceptors. This provides novel insights into the use of these luminogens in optical applications.</subfield></datafield><datafield tag="650" ind1=" " ind2="7"><subfield code="a">Aggregation-induced emission enhancement</subfield><subfield code="2">Elsevier</subfield></datafield><datafield tag="650" ind1=" " ind2="7"><subfield code="a">Intramolecular charge-transfer</subfield><subfield code="2">Elsevier</subfield></datafield><datafield tag="650" ind1=" " ind2="7"><subfield code="a">dicyanoethylene</subfield><subfield code="2">Elsevier</subfield></datafield><datafield tag="650" ind1=" " ind2="7"><subfield code="a">Carbazole</subfield><subfield code="2">Elsevier</subfield></datafield><datafield tag="650" ind1=" " ind2="7"><subfield code="a">Mechanofluorochromism</subfield><subfield code="2">Elsevier</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Zhou, Ningning</subfield><subfield code="4">oth</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Zhou, Juanfang</subfield><subfield code="4">oth</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Zhang, Weidong</subfield><subfield code="4">oth</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Liu, Xingliang</subfield><subfield code="4">oth</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Xu, Defang</subfield><subfield code="4">oth</subfield></datafield><datafield tag="773" ind1="0" ind2="8"><subfield code="i">Enthalten in</subfield><subfield code="n">Elsevier</subfield><subfield code="a">Liu, Chang ELSEVIER</subfield><subfield code="t">New ablation evolution behaviors in micro-hole drilling of 2.5D C</subfield><subfield code="d">2021</subfield><subfield code="g">New York, NY [u.a.]</subfield><subfield code="w">(DE-627)ELV00662605X</subfield></datafield><datafield tag="773" ind1="1" ind2="8"><subfield code="g">volume:252</subfield><subfield code="g">year:2022</subfield><subfield code="g">pages:0</subfield></datafield><datafield tag="856" ind1="4" ind2="0"><subfield code="u">https://doi.org/10.1016/j.jlumin.2022.119323</subfield><subfield code="3">Volltext</subfield></datafield><datafield tag="912" ind1=" " ind2=" "><subfield code="a">GBV_USEFLAG_U</subfield></datafield><datafield tag="912" ind1=" " ind2=" "><subfield code="a">GBV_ELV</subfield></datafield><datafield tag="912" ind1=" " ind2=" "><subfield code="a">SYSFLAG_U</subfield></datafield><datafield tag="936" ind1="b" ind2="k"><subfield code="a">51.60</subfield><subfield code="j">Keramische Werkstoffe</subfield><subfield code="j">Hartstoffe</subfield><subfield code="x">Werkstoffkunde</subfield><subfield code="q">VZ</subfield></datafield><datafield tag="936" ind1="b" ind2="k"><subfield code="a">58.45</subfield><subfield code="j">Gesteinshüttenkunde</subfield><subfield code="q">VZ</subfield></datafield><datafield tag="951" ind1=" " ind2=" "><subfield code="a">AR</subfield></datafield><datafield tag="952" ind1=" " ind2=" "><subfield code="d">252</subfield><subfield code="j">2022</subfield><subfield code="h">0</subfield></datafield></record></collection>
