Abstract

In this structure-property correlation study we have investigated a number of novel disc-shaped compounds incorporating a 1,3,5-trisubstituted benzene at the central core. All the materials with peripheral arms attached through an ester linkage exhibited a columnar phase (Col(r) or Col(h)). The sole use of core-OOC-arm ester linkages resulted in a Col(r) phase, whereas any inclusion of a core-COO-arm linkage caused a Col(h) phase. We suggest that columnar mesophases are being generated due to space being occupied in the peripheral regions by the gradual offset stacking of individual molecules in the self-organised phase structure.
