Oligo(p-phenylene)s containing hydroxyl group(s), namely, OPP(n)-OH (n=3, 4, and 5; it denotes the number of benzene rings), HO-OPP(3)-OH, and 1,3,5-tri(4-biphenyl)phenol TBP-OH were synthesized in high yields by the Suzuki coupling reaction. Absorption maxima (lambda(max)s) of OPP(n)-OHs shifted progressively toward long wavelengths due to the expansion of the pi-conjugation system with an increase in the number of benzene rings. Deprotonation of the OH group of OPP(n)-OHs by treatment with NaH caused a bathochromic shift of lambda(max). The bathochromic shift of the deprotonated species increased with the donor numbers (DNs) of the solvents. The emission peak positions of OPP(n)-OH and OPP(n)-ONa depended on the DN of the solvents; that is, the emission color could be tuned by changing the solvent. (C) 2009 Elsevier Ltd.

A compound of formula (I) or a dimer thereof; where R?1 and R2¿ are independently selected from optionally substituted alkyl, optionally substituted alkenyl, optionally substituted alkynyl, a functional group or a group of sub-formula (i) where m is 0 or 1; p is an integer of from 1 to 12; R7 is a group of formula -C¿q?X2q+1 where q is an integer of from 1 to 12 and X is halogen such as fluoro, or ?7¿ a group of sub-formula (ii) where k is an integer of from 1 to 10, R?8, R10, and R12¿ and each R?9 and R11¿ are independently selected from alkyl, alkenyl or aryl, such as lower alkyl and in particular methyl; provided that at least one of R1 or R2 is a group of sub-formula (i); R?3, R4, R5 and R6¿ are independently selected from hydrogen or halogen, and in particular fluorine, n is 0 or 1, and A is a ring structure as specified. Compounds of formula (I) may have liquid crystal properties and/or be useful in liquid crystal devices.
