Synthesis, Photo-physical and Electrochemical Properties of Dendrimers with (S)-BINOL Core

Chiral dendritic architectureswith benzothiazole as surface group, 1,2,3-triazole as a bridging unit, and (S)-BINOL (1,1-bi-2-naphthol) as a core unit were synthesised in good yields via a convergent synthetic strategy. The chiroptical properties of the dendrimers revealed that the specific rotation increased in the order of dendrimers 4. 3. 2. 1. All the dendrimers showed excellent optical and electrochemical response, and hence would find application in dye-sensitised solar cells
