DOI: 10.1021/acs.macromol.7b00883
Abstract: We recently reported that tetraphenylethene-appended poly(acrylic acid) derivatives [PAA-TPEx (x = 0.01–0.05)] provide a fluorescent Ca2+ sensor, where aggregation-induced emission (AIE) of the TPE pendants occurs in conjunction with Ca2+-triggered polymer-chain folding. On the basis… read more here.
