Synthesis and Optical Properties of Some Compounds Based on Carbazole and s-Triazine
A hyperbranched conjugated polymer (P), as well as its repeating units (M), have been synthesized based on 2,4,6-trimethyl-s-triazine and formylcarbazole. Compared with M, P exhibits much stronger fluorescenee and a larger Stern-Volmer constant (K-SV) in response to DNT, indicating a fluorescence signal amplification effect in the hyperbranched conjugated polymer P.
