16. The ESI-MS measurements were conducted in the presence of excess sodium iodide in chloroform-methanol solutions, which led to the observations of sodium adduct ion peaks in a positive ion mode.
17. The CSI-MS measurements were conducted in dichloromethane solutions, which exhibited the chloride adduct ion peaks in a negative ion mode.

22. Reproducible experimental results were obtained from the time-resolved fluorescence measurements of the three samples operated under anaerobic and aerobic conditions. This indicates the anthracene groups incorporated within the dendritic architectures were tolerant of oxidative degradation on the time scale of the decay runs.
23. To understand a general trend in changes in fluorescence decay profiles for the branching series of dendritic architectures, the dynamic process of 3B was also examined by the time-resolved techniques under the same conditions employed for the other cases. As a result, 3B was found to exhibit anomalous behavior in the fluorescence intensity traces decaying much faster than those of the other samples examined, which was quite difficult to be rationalized on the basis of the interpretations stated above. Details on these experimental results will be discussed elsewhere.
