Aggregation-enhanced emission (AEE)-active polyamides with methylsulfonyltriphenylamine units for electrofluorochromic applications

Abstract: a b s t r a c tIn this work, a series of AEE-active polyamides containing methylsulfonyltriphenylamine units were prepared from a newly synthesized diamine "4,4 0 -diamine-4 00 -methylsulfonyltriphenylamine" and three dicarboxylic acids, which were highly soluble in various organic solvents and exhibited outstanding thermostability. The resulting polymer films showed one reversible redox couple along with apparent color changing from colorless to purple. The polymer solutions revealed relatively weak fluoresce… Show more

“…The resultant polymer nanofibers showed an interesting electrofluorochromic performance in polarized photoluminescence . Fluorescent polytriphenylamines was also prepared and reported as electroflorochromic materials . Approving electrofluorochromic performance was displayed, ascribing to effective mitigation of aggregation‐caused quenching effect benefiting from unique propeller starburst structure of triphenylamine.…”

[24][25][26][27][28][29] Approving electrofluorochromic performance was displayed, ascribing to effective mitigation of aggregation-caused quenching effect benefiting from unique propeller starburst structure of triphenylamine. For better understanding of electrofluorochromic mechanism and expansion of practical applicability, electrofluorochromic polymers need to be further explored.…”

“…This strategy is expected to afford sulfone‐cointaing materials with enhanced emission quantum yields [ 118–122 ] and blue‐shifted emission, due to the sulfonyl electron‐withdrawing ability. [ 123 ] Indeed, the TPA‐MeS polymer films have λ max at 475 nm and, in the neutral state, exhibit a cyan fluorescence which is slightly enhanced with respect to that in solution, thus showing a moderate AIE effect. However, among the polymers investigated, only that with R = cyclohexyl in the backbone has a rather high photoluminescence quantum yield (32%).…”

“…Electroactive triphenylamine is a key building block for EC materials due to its ability to form stable radical cations at the nitrogen atom upon oxidation [30]. Three polyamides, P7a – c , containing sulfone groups substituted on triphenylamine were reported [53]. Amongst the three polyamides, P7a reveal aggregation-enhanced emission (AEE) properties with a high solid state ϕ f of 32.1% and a remarkably high switching contrast of 234.…”
