Switchable Columnar Phase Formed from Bent-Shaped Molecules with Low Bent-Angle Naphthalene Central Core and Alkylthio Tail
摘要:
Novel low-angle bent molecules with 1,7-naphthalene central core and alkylthio tails form the hexagonal columnar phase as well as the well-known B4 phase. The columnar phase has a large two-dimensional hexagonal lattice of 65-70 angstrom and exhibits the antiferroelectric switching with the spontaneous polarization along the column axis. The column is considered to be constructed by the cylindrically enclosed layer.

A series of 4-substituted phenylguanidinium derivatives was synthesized and its antimicrobial activity was evaluated in vitro against eight potentially pathogenic strains of fungi.
