N2 - Three AIE-active positional isomers, TPE-4(Ph-o-CHO), TPE-4(Ph-m-CHO) and TPE-4(Ph-p-CHO), which are tetraphenylethylene (TPE) derivates peripherally attaching ortho-/meta-/para-formyl phenyl groups, were designed and synthesized. The formyl substitution position caused different intramolecular charge transfer (ICT) of the isomers, which can effectively modulate their photophysical properties and mechanochromism. TPE-4(Ph-o-CHO), TPE-4(Ph-m-CHO) and TPE-4(Ph-p-CHO) exhibited remarkable aggregation-induced emission (AIE) characteristics. Moreover, TPE-4(Ph-o-CHO), TPE-4(Ph-m-CHO) and TPE-4(Ph-p-CHO) possessed mechanochromic property, which displayed distinguished color changes. Thus, three isomers are potential to be applied in mechano-response sensors or optical storage materials.
