Yamaguchi, Isao; Fukumoto, Daiki; Wang, Aohan published the artcile< Synthesis and optical properties of pi-conjugated polymers and oligomers bearing hexaphenylbenzene and tetraphenyl ethene units>, Reference of 184239-35-8, the main research area is hexaphenylbenzene tetraphenylethene polymer preparation optical property.

π-Conjugated polymers (CPs) and oligomers (COs) bearing hexaphenylbenzene (HPB) and tetra-Ph ethene (TPE) units were synthesized by Sonogashira and Suzuki-Miyaura coupling reactions. The optical properties of the CPs and COs were investigated by UV-vis, photoluminescence (PL), and fluorescence lifetime (τ) measurements. The PL intensities of the solutions of the CPs and COs synthesized by Sonogashira coupling were reduced upon addition of poor solvent like water, which is attributed to aggregation-caused quenching. In contrast, the CP and COs bearing the TPE unit synthesized by Suzuki-Miyaura coupling exhibited aggregation-induced emission enhancement in solution This difference in fluorescence behavior is discussed herein in terms of the mol. sizes, conformations in solution, and τ values of the CPs and COs.
