Confined-domain crosslink-enhanced emission effect in carbonized polymer dots. (IMAGE)
Caption
a, Schematic of the “addition-condensation polymerization” strategy to investigate the confined-domain CEE in CPDs. b, Schematic of the relationship between the methyl groups and the internal structure of CPDs (d1: the spacing of the original skeleton inside CPDs without methyl groups. d2: the spacing of the stretched skeleton inside CPDs by methyl groups. n: the amount of introduced methyl groups in CPDs. D: the average skeleton spacing of CPDs). c, RTP lifetimes in solid state and QYs in solution state of CPDs with different contents of methyl groups. d, Schematic effect of confined-domain CEE on the energy levels of CPDs (IC: internal conversion, Abs.: absorption, Fluo.:fluorescence, Phos.: phosphorescence).
