Abstract

The crosslink enhanced emission (CEE) in a new type of non-conjugated polymer dots (PDs) is proved. The enhanced PL originates from the decreased vibration and rotation of amino-based chromophores. Furthermore, the cellular uptake mechanism and internalization of PDs were investigated in detail.
