Abstract: Methylation of TPA-DCM (2-(2,6-bis-4-(diphenylamino)stryryl-4H-pyranylidene)malononitrile) that exhibits aggregation-caused quenching (ACQ) results in the fluorophore M-TPA-DCM (2-(2,6-bis((E)-4-(di-p-tolylamino)-styryl)-4H-pyran-4-ylidene]malononitrile) that shows aggregation-induced emission (AIE) and NIR fluorescence and has a conjugated "D-π-A-π-D" electronic configuration. Friedel-Crafts reaction of TPA-DCM and… read more here.
