Nonconventional photoluminescence from sulfonated acetone–formaldehyde condensate with aggregation-enhanced emission†
Abstract
The fluorescence of sulfonated acetone–formaldehyde condensate (SAF) with a nonconventional chromophore is reported for the firsttime. The fluorescence intensity of SAF can be enhanced by the introduction of phenols to obtain sulfonated phenol–acetone–formaldehyde (SPAF) and the emission color can be changed. Both of them show aggregation-enhanced emission (AEE) properties.
