TPE-NCS

Aggregation induced emission (AIE) is a kind of phenomenon that molecules in solution which do not emit light or have weak luminescence enhance their luminescence after aggregation.Single TPE molecules are arranged orderly in TPE NCS,which limits the intramolecular free rotation of benzene ring,reduces the non radiative relaxation and further enhances ECL.Compared with the blue fluorescence emitted by the band gap transition of TPE NCS,the ECL spectrum of TPE NCS is red shifted to the near infrared region (678 nm),Compared with the traditional near-infrared ECL luminescent materials,tetrastyrene nanocrystals (TPE NCS) improve the electron hole recombination efficiency by aggregating TPE molecules,inhibit the non radiative transition,and realize the aggregation induced enhanced ECL emission.
