Inspired by naturally occurring helical supramolecular architectures, a series of chiral conjugated phospholes with a cholesteryl pendant have been synthesized and characterized. The photophysically and electrochemically active conjugated phosphole species can act as dopants for the formation of chiral liquid crystals. The supramolecular structures were found to be tunable by careful choice of the conjugated headgroup as well as the rigidity of the linker of the new cholesteric phospholes.

the gel, which was further evidenced by 1H-NMR and SEM analysis. However, the gel stability of BCIE was enhanced by the addition of Pd2+ and Zn2+ in the presence of pyridine, whereas the gel collapsed in other solvents, which may be due to the chelatingeffect of the pyridine moiety. Another interesting feature of this gel is that when using the gelator as a stabilizer, stable water in oil (W/O) gel-emulsions
