Very recently, Shinkai et al. (see Ref. 200) synthesized tri-dendron type dendrimers (generation = 1 and 2). The branch cell reagent shown below was utilized in a convergent approach to synthesize the dendrons. These dendrons were then anchored in each case around a 1,3,5-benzene tricarbonyl chloride core. This...

It was found that the benzene, toluene, mesitylene, durene and hexamethylbenzene tricarbonyl chromium could best be separated and quantitatively determined in mixtures by use of temperature programming with the flame ionization detector. Figure 204 illustrates the separation achieved. It can be seen that the resolution is excellent, and that the retention times of the early components are far enough removed from the tail of the solvent peak that measurements from the original base line are possible in each case. Under isothermal conditions (135°C) using flame ionization, the benzene tricarbonyl--chromium and toluene tricarbonylchromium peaks eluted on the tail of the benzene peaks and the retention time of the hexamethylbenzene tricarbonylchromium was 32.6 minutes. This peak was also considerably broader and flatter when eluted isothermally. For this determination therefore, programmed temperature operation is the most efficient means of analysis not only is the resolution improved, but also the total time of analysis is reduced to 15 minutes.

The attempts of Bryce [21] to make aryl ester dendrimers decorated with external tetrathiofulvalene (TTF) revolved around the same approach as that of Miller and Neenan. Bryce et al. [21] started from a phenol containing two ester TTF moieties and used 5-tert-butyldimethylsilylisophthalic chloride as the building block. 1,3,5-Benzene tricarbonyl chloride was taken as the central core to couple second-generation dendrons. The second-generation dendrimer aryl ester dendrimers fitted with 12 terminal TTF units were then oxidized. Investigation of their redox behavior showed that simultaneous electron transfer did occur.
