Taper Shaped and Dendritic Molecules Leading to Curved Aggregates

2 Taper Shaped and Dendritic Molecules Leading to Curved Aggregates 

1 The Influence of Fluorophobic Effect and Size Effects on Self-Assembly 

Whereas the mesophase morphologies of compounds 35-37 depend on the size ratio of polar and apolar segments, the mesophase stabilities are mainly influenced 

It should also be noted that the stability of the distinct mesophases can be quite different. It seems that there is a significant effect of molecular shape and topology, stabilizing SmA phases in the system 41/43 and Colhex phases in the system 35/37. In addition, the mesophase stability is often reduced close to the transition to another mesophase (see Fig. 15). Hence, the order-disorder temperatures can only be roughly estimated based on segmental solubility parameters [24, 25]. 

Dendritic molecules, forming predominately hexagonal columnar and micellar cubic phases, have been introduced and intensively investigated by Percec et al. and this field has recently been reviewed [143], The mesophases of these dendrons can also be stabilized and modified by replacing alkyl chains by fluorinated chains selected examples will be discussed in the next sections.
