Abstract
Carbosilane dendrimers with 2-(2-phenyloxy)benzothiazole groups on the periphery were prepared from the 1st to the 7th generation. All dendrimers were characterized by 1H- and 13C-NMR, elemental analysis, MALDI TOF MS, GPC, and PL (photoluminescence) spectroscopy. Characteristic PDI (Polydisperse Index) values of the peaks corresponding to the respective dendrimers in the GPC data is in very narrow range of 1.00~1.04. All PL spectra show a blue-shift increasing with generation from the 1st to the 7th.
Highlights
Confirmation of dendrimer isomolecularity has been a controversial subject due to their architectural similarity, especially in the case of higher generations [1,2,3]
Uniformities in size of these carbosilane dendrimers were determined by gel permeation chromatography (GPC)
The same hydrosilation and substitution reaction were repeated for the preparation of dendrimers from generations 1 to 7
Summary
Confirmation of dendrimer isomolecularity has been a controversial subject due to their architectural similarity, especially in the case of higher generations [1,2,3]. The isomolecularity of low generation dendrimers, with molecular weights around a few thousand Daltons, has been confirmed by mass spectroscopy [4,5,6]. Uniformities in size of these carbosilane dendrimers were determined by GPC
