Chiral dendritic architectures with 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.

Abstract:

Two different metal-organic frameworks (MOFs) [Cd2(AZN)(HAZN)(btc)(Hbtc)·4H2O]·2H2O (1), and [Zn3(AZN)2(btc)2·4H2O] (2) were synthesized by the reactions of different metal salts with mixed ligands of 1-(4-(1H-imidazol-5-yl)phenyl)-1H-1,2,4-triazole (AZN) and trimesic acid (H3btc). The different metal centers in the reaction condition have important impact on the resulting structures of MOFs 1 and 2. Compound 1 is a one-dimensional (1D) chain structure, while 2 features a three-dimensional (3D) framework with 3-fold interpenetration topology of Point (Schläfli) symbol of (6·82)4(62·82·102). Fu
